If this inclined plane moves 3 cm to the left how high will it lift the object

If This Inclined Plane Moves 3 Cm To The Left How High Will It Lift The Object

Answers

Answer 1

Answer:

It would lift the object to the same height than before you move it 3 centimeters to the left. You see, the height doesn't change if you move the inclined plane horizontally, because height is a vertical variable.

Therefore, if the inclined plane has a height of 1 meters, then the object will be lifted 1 meters up, no matter if you move the inclined plane 50 meters horizontally, it won't change its height.

Which has greater kinetic energy: a bullet that has a mass of 0.05 kg travelling at 2500 m/s, or a lorry that has a mass of 4500 kg and is moving at 50 m/s?

Answers

Answer:

its the lorry

Explanation:

The kinetic energy of the truck will be, 5625000 kg m/s and the kinetic energy of the bullet will be 156250 kg m/s. So the kinetic energy of the lorry will be higher than the kinetic energy of the Bullet.

What is Kinetic Energy?

Kinetic energy is a type of energy that a particle or an object possesses as a result of its motion. By exerting a net force on an item, work is done, which transfers energy; as a result, the object accelerates and obtains kinetic energy.

A moving item or particle's ability to move depends on both its mass and velocity. This is known as kinetic energy. Translation (or movement along a path from one location to another), rotation about an axis, vibration, or any combination of motions are examples of possible types of motion.

According to the question,

K.E of the lorry: 1/2 (4500)(50)²

K.E of the lorry = 5625000 kg m/s.

K.E of the bullet: 1/2(0.05)(250)²

K.E of the bullet = 156250 kg m/s

Hence, the kinetic energy of the lorry is greater than the kinetic energy of the bullet.

A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of the velocity and the acceleration of the brush as it falls? Pick the two answers. The velocity increases. The velocity decreases. The velocity remains a constant value. The acceleration increases. The acceleration decreases. The acceleration remains a constant value.

Answers

Answer:

Explanation:

As the paint brush is dropped from the top of a tall ladder it started free falling

i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.

We know acceleration due to gravity is the attraction experienced by the object due to earth attraction

Value of acceleration due to gravity is constant i.e. [tex]9.8\ m/s^2[/tex]

Therefore the correct choice is

velocity is increasing and acceleration is constant

Corrected question;

Chef Andy tosses an orange in the air, then catches it again at the same height. The orange is in the air for 0.75 s. We can ignore air resistance. What was the orange's velocity at the moment it was tossed into the air?

Explanation:

Applying the equation of motion;

v = u + at. ....1

Where

u = initial speed

v = final speed

a = acceleration

t = time taken

Given;

Total time of flight t = 0.75s

Acceleration due to gravity g = 9.8 m/s^2

Considering the first phase of flight, during the upward motion to the maximum height. The final velocity at the maximum height is zero and the time of flight of the phase is equal to half of the total flight time.

v1 = 0

t1 = t/2 = 0.75/2 =0.375s

From equation 1;

v1 = u - gt1

Substituting the values;

0 = u - 9.8(0.375)

Solving for u;

u = 9.8(0.375)

u = 3.675

u = 3.68 m/s

Initial velocity = 3.68 m/s

A car is going 60.0 mi/h and has to stop in 6.0 seconds. What is the car’s acceleration?

Answers

Explanation:

Convert mi/h to ft/s.

60.0 mi/h × (5280 ft/mi) × (1 h / 3600 s) = 88.0 ft/s

Find the acceleration.

a = Δv / Δt

a = (0 ft/s − 88.0 ft/s) / 6.0 s

a = -14.7 ft/s²

Calculate the energy that 1.5 kg of mass contains

Answers

Answer:

[tex]4.5(10)^8[/tex] joules

Explanation:

Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.

The relation between energy and mass is given by [tex]E=mc^2[/tex]

Here, E denotes energy, m denotes mass and c denotes speed of light

Mass [tex](m)=1.5\,\,kg[/tex]

Speed of light (c) = 3 × [tex]10^8[/tex] m/s

Therefore,

[tex]E=1.5(3)(10)^8=4.5(10)^8[/tex]  joules.

The S.I. unit of energy is joules which is equal to [tex]1\,\,kg\,\,m^2/s^2[/tex]

How does the current values in and out of the battery compare to the sum of currents going through the light bulbs?

Note: This is for Parallel circuits.

Answers

The current values in and out of the battery is going to be equal to the sum of the currents going through the light bulbs. In a parallel circuit, the current is divided as it enters different branches and light bulbs. However, the amount of current leaving the battery is always going to be the same as the amount of current entering the battery. Therefore, while current divides in a parallel circuit, the total amount of current always remains the same.

How does visible light interact with objects to produce the colors we see?​

Answers

Answer:

Visible light when all put together is white. When objects appear to be, lets say, red, it would be the only color not absorbed by that object. same goes with all other colors. So black objects absorb all colors (not 100%) and that is why black clothing gets hotter, it simply absorbs all incoming light, as apposed to white that will reflect the colors back, making all of them together appear white.

Read the scenario. A car starts 10 m north of a reference point. It moves at a constant velocity over the next 5 s, reaching a position of 10 m south of the reference point. What is the car’s average velocity? 2 m/s south 4 m/s north 0 m/s 4 m/s south

Answers

Answer:

4 m/s south

Explanation:

This is a pretty easy one.

Assume that the car has a reference point ragged x

We also know that the car starts moving at a point 10 m North of X. It moves steadily at a uniform velocity and ended at a position 10 m south of X.

If x is the reference point, we can infer that the car moves a total distance of, 10 m + 10 m.

Thus, the total distance moved by the car is 20 m.

It is also stated that it achieves that distance in 5 seconds.

Velocity is defined as the ratio of distance with respect to the tome taken, i.e V = d/t

Then, the velocity is

V = 20 / 5 = 4 m/s

Considering the fact that the car left and moved towards the south. We can say that it moved 4 m/s South.

A 25.2 kg gazelle moving 2.33 m/s
sees a lion, and exerts a 113 N
force to accelerate. How fast is
it moving 2.00 s later?

Answers

Force = mass x acceleration
113N = 25.2a
a = 4.48 m/s^2
Vf = Vi + at
Vf = 2.33 + 4.48(2) = 11.3 m/s

The velocity of the gazelle after 2 seconds is equal to 11.3 m/s.

What is the equation of motion?

The equations of motion have described the relationship between the time, velocity, acceleration, and displacement of a moving object.

The equations of motions can be described as shown below:

[tex]v = u + at\\S = ut +\frac{1}{2}at^2 \\ v^2-u^2 = 2aS[/tex]

Given the mass of the gazelle, m = 25.2 Kg

The force acting to accelerate, F = 113N

The acceleration in the speed of gazelle is given by: a = F/m

a = 113/ 25.2

a = 4.48 m/s²

The initial speed of the gazelle, u = 2.33 m/s

From the first equation of motion we can calculate the final velocity of the  gazelle:

v = u + at

v = 2.33 + (4.48) (2)

v = 11.3 m/s

Therefore, the velocity of the gazelle 2 seconds later is 11.3 m/s.

Um joalheiro recebe uma encomenda onde ele deve fazer alguns anéis de prata.

O principal problema desse procedimento é que a temperatura de fusão da prata é muito alta e requer condições especiais. A prata possui temperatura de fusão de 961 ºC, calor latente de fusão de 21 cal/g e calor específico no estado sólido igual a 0,056 cal/gºC. Determine a quantidade de calor aproximada para fundir as 100 g de prata sabendo que sua temperatura inicial é de 20°C. A 2,1 kcal B 0,5 kcal C 7,4 kcal D 5,3 kcal E 6,3 kcal

Answers

Answer:

Correct option: C -> 7.4 kcal

Explanation:

First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:

941 * 0.056 * 100 = 5269.6 cal

Then, for the melting process, we will need:

21 * 100 = 2100 cal

So the total energy needed is:

5269.6 + 2100 = 7369.6 cal = 7.4 kcal
