Answer:

v = 26.54 m/s

Explanation:

Given that,

The mass of a hockey puck, m = 0.21 kg

The kinetic energy of the hockey puck, E= 74 J

We need to find the speed of the hockey puck. Let the speed is v. We know that, the kinetic energy is given by :

[tex]E=\dfrac{1}{2}mv^2[/tex]

Where

v is the speed

So,

[tex]v=\sqrt{\dfrac{2E}{m}} \\\\v=\sqrt{\dfrac{2\times 74}{0.21}} \\\\v=26.54\ m/s[/tex]

So, the speed of the hockey puck is 26.54 m/s.

Answer:

You did not include the picture but I found a similar question that I can explain and you can then use to answer yours.

The middle scale is in hundreds. The arrow here is pointing to 100 so the mass of the object is more than 100g but less than 200g.

The highest scale is in 10s. The arrow is pointing to 0. This means that the object weighs more than 100 but less than 110 g. If the arrow was pointing to 10 then the object would weigh more than 110g.

The bottommost scale is in 1s. Notice how the scale is pointing to 5.7 grams. The object is therefore 105.7 grams.

Look for the option closest to this because the 105.7g might be rounded up.

You will then find 105.65g as your answer.

Answer:433.0 g

Explanation:i’m not 100% sure

Answer:

Explanation:

What you forgot to include is the mass of the earth, which is 5.98 × 10²⁴ kg. NOW we can do the problem:

[tex]F=\frac{Gm_1m_2}{r^2}[/tex] where m1 and m2 are the masses of the objects experiencing this force of gravity, F. G is the universal gravitational constant. Filling in:

[tex]2.00*10^{20}=\frac{(6.67*10^{-11})(7.34*10^{22})(5.98*10^{24})}{r^2}[/tex]

We are going to rearrange and solve for r before we do any math on this thing:

[tex]r=\sqrt{\frac{(6.67*10^{-11})(7.34*10^{22})(5.98*10^{24})}{2.00*10^{20}} }[/tex] and when we plug all that mess into our calculators we will do it just like that and then round to 3 significant digits at the very end.

Doing all of that gives us that

r = 3.83 × 10⁸ m

Answer:

Energy band theory is a basis for describing processes and effects in solid crystals under electromagnetic field impact.

Explanation:

Single atoms have a discrete energy spectrum, which means they can occupy only discrete energy levels. Part of these energy levels are filled with electrons in a non-excited condition. Part of these levels can be occupied only when electrons are excited.

Answer:

The correct answer is "470.4 N".

Explanation:

Let the system moves downwards with acceleration "a",

then,

⇒ [tex]a = \frac{Net \ external \ force}{Net \ mass}[/tex]

      [tex]=\frac{(m_2+m)g}{(m_2+m_1+m)}[/tex]

      [tex]=\frac{440+60}{(440+2000+60)}[/tex]

      [tex]=\frac{500\times 9.8}{2500}[/tex]

      [tex]=1.96 \ m/s^2[/tex]

The apparent weight will be:

⇒ [tex]mg-F_A=ma[/tex]

or,

⇒ [tex]F_A=mg-ma[/tex]

         [tex]=m(g-a)[/tex]

By substituting the values, we get

         [tex]=60(9.8-1.96)[/tex]

         [tex]=470.4 \ N[/tex]        

Answer:

Force = 4.25 Newton

Explanation:

Given the following data;

Mass = 10 kg

Momentum = 15 Kgm/s

Time, t = 20 seconds

Final velocity, V = 10 m/s

To find the average force required;

First of all, we would determine the initial velocity of the object.

Momentum = mass * velocity

15 = 10 * velocity

Velocity = 15/10

Velocity = 1.5 m/s

Next, we would determine the acceleration of the object by using the first equation of motion;

V = U + at

10 = 1.5 + a*20

10 - 1.5 = 20a

8.5 = 20a

Acceleration, a = 8.5/20

Acceleration, a = 0.425 m/s²

Lastly, we would find the average force by using the formula;

Force = mass * acceleration

Force = 10 * 0.425

Force = 4.25 Newton

Answer:

The road surface is always rough, so the frictional force between the tires and the road surface make it difficult to maintain constant speed because acceleration always changes.

Answer:

Mass, m = 146.72 kilograms

Explanation:

Given the following data;

Kinetic energy = 190 J

Velocity = 2.59 m/s

To find the combined mass of the girl and her bike;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = ½mv²

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

190 = ½*m*2.59

Cross-multiplying, we have:

380 = 2.59m

Mass, m = 380/2.59

Mass, m = 146.72 kilograms

Density = Mass/Volume

=> 5g/cm³ = 45kg/Volume

=> 0.005kg/cm³ = 45kg/Volume

=> Volume = (cm³×45kg)/0.005kg

=> Volume = 9000kg/cm³

5 grams fits into 45 kg 9,000 times.

Since each 5 grams occupies 1 cm³, 9,000 little packages of 5 grams must occupy 9,000 cm³ .  (That's 9 liters.)

Explanation:

1ml = 2.7g

Xml = 1.5g

Divide 1.5 by 2.7 to find X.

Obviously, since 1.5 is less than 2.7, you know the answer will be less than 1.

Answer:

D. crystalline solid that conducts current under certain conditions

Explanation:

Semiconductors are crystalline solids that has the ability to conduct electrical currents but on certain conditions e.g heat. The conduction of semiconductors is less than that of conductors (metals) but more than insulators (nonmetals), hence, they are said to be intermediates of conductors and insulators in terms of electrical conductivity.

Examples of semiconductors are silicon, boron, carbon, germanium, arsenic etc.

Answer:

The final displacement of the car is 140 meters.

Explanation:

The final displacement of the car ([tex]s[/tex]), in meters, is the sum of the change in displacement associated with each part of the journey, which is derived from the following kinematic formulas:

[tex]s = s_{1} + s_{2}[/tex] (1)

[tex]s_{1} = \frac{1}{2}\cdot a_{1}\cdot t_{1}^{2}[/tex] (2)

[tex]v_{o,2} = a_{1}\cdot t_{1}[/tex] (3)

[tex]s_{2} = v_{o,2} + \frac{1}{2}\cdot a_{2}\cdot t_{2}^{2}[/tex] (4)

Where:

[tex]s_{1}[/tex] - Traveled distance of the first part, in meters.

[tex]s_{2}[/tex] - Traveled distance of the second part, in meters.

[tex]a_{1}[/tex] - Acceleration in the first part, in meters per square second.

[tex]a_{2}[/tex] - Acceleration in the second part, in meters per square second.

[tex]v_{o,2}[/tex] - Initial speed of the car in the second part, in meters per second.

[tex]t_{1}[/tex] - Time taken in the first part, in seconds.

[tex]t_{2}[/tex] - Time taken in the second part, in seconds.

If we know that [tex]a_{1} = 0.8\,\frac{m}{s^{2}}[/tex], [tex]t_{1} = 10\,s[/tex], [tex]a_{2} = 0.4\,\frac{m}{s^{2}}[/tex] and [tex]t_{2} = 10\,s[/tex], then the distance traveled by the car is:

By (2):

[tex]s_{1} = \frac{1}{2}\cdot \left(0.8\,\frac{m}{s^{2}} \right)\cdot(10\,s)^{2}[/tex]

[tex]s_{1} = 40\,m[/tex]

By (3):

[tex]v_{o,2} = \left(0.8\,\frac{m}{s^{2}} \right)\cdot (10\,s)[/tex]

[tex]v_{o,2} = 8\,\frac{m}{s}[/tex]

By (4):

[tex]s_{2} = \left(8\,\frac{m}{s} \right)\cdot (10\,s) + \frac{1}{2}\cdot \left(0.4\,\frac{m}{s^{2}} \right)\cdot (10\,s)^{2}[/tex]

[tex]s_{2} = 100\,m[/tex]

By (1):

[tex]s = 140\,m[/tex]

The final displacement of the car is 140 meters.

Answer:

it means that the force of attraction between two object in gravitation is 6.67×10-11N

It means that the force of attraction between two object in gravitation is 6.67×10-11N.

The formula is g = GM/r2, Where M is the mass of the Earth, r is the radius of the Earth (or distance between the center of the Earth and you, standing on its surface), and G is the gravitational constant. G (without the subscripts) is the gravitational constant, and c is the speed of light.

The gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between their centers. joining the two centers of masses.

magnitude is area. hope it helps.

Answer:

Systems always tend toward a state of decreasing order unless more energy is provided into the system to counteract this tendency.

Answer:

The effect of gravity extends from each object out into space in all directions, and for an infinite distance. However, the strength of the gravitational force reduces quickly with distance. Humans are never aware of the Sun's gravity pulling them because the pull is so small at the distance between the Earth and Sun.

Answer:

The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

Explanation:

Una partícula efectúa un MAS cuya ecuación es: x=0.3cos (2t + π/6) m. Determinar: Amplitud, frecuencia angular, fase inicial, periodo, frecuencia de oscilación y posición en t=0.25 s

Solution:

La ecuación de la onda es:

x = A cos (ω t + Ф), donde:

A = amplitud, ω = frecuencia angular = 2 π / T = 2 π f, Ф = fase inicial, f = frecuencia, T = período

Por lo tanto, comparando la ecuación de la onda con x = 0.3cos (2t + π / 6), obtenemos:

a) A = 0.3

b) ω = 2 rad / s

c) Ф = π / 6 rad

d) ω = 2π / T

2 = 2π / T

T = 3.14 s

e) ω = 2πf

2 = 2πf

f = 0.32 Hz

f) en t = 0.25 s:

x (t) = 0.3cos (2 * 0.25 + π / 6) = 0.22 m

Answer:

1875 J of energy is converted to heat.

Explanation:

Given that,

The combined mass of Andrea and the bike is 50 kg

Initial speed of Andrea's bicycle, u = 10 m/s

Final speed of Andrea's bicycle, v = 5 m/s

The energy converted to heat can be calculated using the work-energy theorem as follows :

[tex]E=\dfrac{1}{2}m(v^2-u^2)\\\\E=\dfrac{1}{2}\times 50\times ((5)^2-(10)^2)\\\\E=-1875\ J[/tex]

So, 1875 J of energy is converted to heat.
