Answer:

Fast rotation

Slow revolution

Explanation:

Solar system has 8 planets. 4 inner rocky planets - Mercury, Venus, Earth and Mars and 4 outer gaseous planets - Jupiter, Saturn, Uranus and Neptune.  The outer planets have few common features.

They are gaseous. There  period of revolution is larger than the inner planets which means that they have slow revolution about the Sun. One day on the outer planets is smaller than the inner planets which means they have fast rotation.

For example, Jupiter has revolves around sun in 11.86 Earth years and rotates about axis in 9.8 Earth hours. Uranus revolves around sun in 84 Earth years and rotates on its axis 17.9 Earth hours.

A mineral is a valuable form of ore that can be extracted from the ground

Explanation:

Gold, quartz and talc are minerals because they are found in the earth in a valuable form of ore while ores are rocks that contain valuable concentrations of minerals.that can be mined.

An ORE in general term can be said to be a mineral deposit that contains enough Minerals that can be mined in commercial quantities while Minerals are valuable components of an Ore that can be mined ( naturally occurring ) in an ORE.

Answer:

0.2

Explanation:

Mechanical Advantage is defined as the ratio of force output with respect to the force input. Thus,

MA = output / input

MA = 5 / 25

MA = 1/5

MA = 0.2

Since this value is less then one. Even though it's tagged a mechanical advantage, in reality it would be mechanical disadvantage.

Therefore, we can say that the mechanical advantage of the baseball bat is 0.2

In mathematics, the difference of two squares is a squared (multiplied by itself) number subtracted from another squared number. Every difference of squares may be factored according to the identity. in elementary algebra.

Explanation:

Answer:

(a) 153.37 g

(b) 5705 kJ

Explanation:

(a) To find the amount of bean needed by a man you first calculate the equivalence in beans to 2500kJ

[tex]2500kJ*\frac{100g}{1630kJ}=153.37\ g[/tex]

Thus, 153.37 g has the energy needed by a man that needs 200kJ per day.

(b) The amount of energy per pot of bean is given by:

[tex]E=350g*\frac{1630kJ}{100g}\\\\E=5705\ kJ[/tex]

Thus, the energy is 5705kJ

Answer: Limiting reactant

Explanation:

The limiting reactant is a reactant will get completely consumed up in the reaction. This reactant being in low concentration will lead to the formation of limited amount of product.

In the given situation, since the butter cakes are required to be 3 sticks for making 3 cakes but only 2 cakes are available thus the butter stick is the limiting reactant.

Answer:

D- a biomass has been used as a part of the fuel.

Answer:

A.The sound waves from the two trombones have slightly different frequencies.

Explanation:

This is because, a difference in frequency of waves from two different sources would result in either constructive or destructive interference of the waves. Thereby, causing the observer to hear the sound increasing or decreasing.

Answer:

A.The sound waves from the two trombones have slightly different frequencies.

Answer:

Nuclear fusion is the process in which two atomic nuclei are fused together into a larger single nucleus, releasing energy in the process. ... In proton-proton fusion, four hydrogen atoms are fused into a single helium-4 atom, releasing a lot of energy in the process.

Explanation:

Answer:

B) Distance and Time

Explanation:

Equation for speed: S = D / T

Speed equals the distance you traveled divided by the amount of time it took to get to that destination.

The two factors which are required to determine the speed of a object are distance traveled by it and time taken by it.

The speed is the rate at which the total distance by a object is traveled in the time taken.

Speed of a object can be given as,

[tex]s=\dfrac{d}{t}[/tex]

Here, (d) is the distance traveled by the object and (t) is time taken but the object to cover that distance.

As the unit of the distance is measured in the meter and the time measure in the second. Thus the speed of a object is measured in the meter per second.

In the vehicles the speed of vehicle is also measured in the kilometre per hour or miles per hour.

Hence, the two factors which are required to determine the speed of a object are distance traveled by it and time taken by it.

Thus the option B is the correct option.

Answer:

0.45 miles

Explanation:

since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\

we will use value of pi as 22/7

Circumference for any circular shape is given by [tex]\piD[/tex][tex]\pi D[/tex]

Hence, in one lap [tex]\pi D[/tex] distance will be covered

in 7 laps [tex]7 \pi D[/tex] distance will be covered.

but is given that 7 laps should be equal to 10 miles

so 10 miles will be equal to [tex]7\pi D[/tex]

[tex]7\pi D= 10 \ miles\\=> 7*(22/7)* D= 10 \ miles\\=> 22D = 10 \ miles\\=> D = 10/22 \ miles\\=> D = 0.45 \ miles[/tex]

Thus, diameter of track will be 0.45 miles to meet the requirement.

Answer:

The moment of inertia decreased by a factor of 4

Explanation:

Given;

initial angular velocity of the ice skater, ω₁ = 2.5 rev/s

final angular velocity of the  ice skater, ω₂ = 10.0 rev/s

During this process we assume that angular momentum is conserved;

I₁ω₁ = I₂ω₂

Where;

I₁ is the initial moment of inertia

I₂ is the final moment of inertia

[tex]I_2 = \frac{I_1 \omega_1}{\omega_2} = \frac{I_1*2.5}{10} \\\\I_2 = 0.25I_1 = \frac{1}{4}I_1[/tex]

Therefore, the moment of inertia decreased by a factor of 4

Explanation:

divide the distance by the time it takes to travel that same distance, then add your direction to it.

Answer:

a. normal

Explanation:

In the field of physics the normal is a line drawn at a right angle to a barrier. In other words the normal line is the line that is drawn perpendicular (right angle, 90 degrees) to the reflective surface of a mirror, or the particular boundary in which refraction occurs at the point of incidence of a light ray. This can be seen in the picture attached below.

Answer:

T = 2.82 seconds.

The frequency [tex]\mathbf{f = 0.36 \ Hz}[/tex]

Amplitude A = 25.5 cm

The maximum speed of the glider is [tex]\mathbf{v = 56.87 \ rad/s}[/tex]

Explanation:

Given that:

the time taken for 11 oscillations is 31 seconds ;

SO, the time taken for one oscillation is :

[tex]T = \frac{31}{11}[/tex]

T = 2.82 seconds.

The formula for calculating frequency can be expressed as :

[tex]f = \frac{1}{T}[/tex]

[tex]f = \frac{1}{2.82}[/tex]

[tex]\mathbf{f = 0.36 \ Hz}[/tex]

The amplitude is determined by using the formula:

[tex]A = \frac{d}{2}[/tex]

The limits that the spring makes the oscillations are from 10 cm to 61 cm.

The distance of the glider is, d = (61 - 10 )cm = 51 cm

Replacing 51 for d in the above equation

[tex]A = \frac{51}{2}[/tex]

A = 25.5 cm

The maximum speed of the glider is:

[tex]v = A \omega[/tex]

where ;

[tex]\omega = \frac{2 \pi}{T}[/tex]

[tex]\omega = \frac{2 \pi}{2.82}[/tex]

[tex]\omega = 2.23 \ rad/s[/tex]

[tex]v = A \omega[/tex]

[tex]v = 25.5 *2.23[/tex]

[tex]\mathbf{v = 56.87 \ rad/s}[/tex]

T1 = T2 = 602.33 N

Explanation:

I attached an image of the forces diagram below.

The x component of the forces for this cases is:

[tex]\Sigma F_x=T_1cos\theta-T_2cos\theta=0\\\\T_1cos\theta=T_2cos\theta\\\\T_1=T_2[/tex]

And the y components:

[tex]\Sigma F_y=T_1sin\theta+T_2sin\theta-W=0\\\\T_1=T_2=T\\\\\Sigma F_y=2Tsin\theta=W\\\\T=\frac{W}{2sin\theta}[/tex]

The angle is calculated by using the information about the length of the cable and the vertical distance of the traffic light:

[tex]\theta=tan^{-1}(\frac{1}{15})=3.81\°[/tex]

Thus, you obtain:

[tex]T=\frac{80N}{2(sin3.81\°)}=601.33N[/tex]

hence, the tension in both segments of the cable is 602.33 N

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
