Answer:

The potential energy of the ball becomes 0

Explanation:

When kicking the ball, and it moves up, the potential energy of the ball increases. When the ball descends downwards, the potential energy of the ball reduces.

This is so because potential energy increases as height increases and decreases when there is a reduction in height.

So, when you stop kicking the ball and you place the ball on the floor, the ball becomes static (motionless); hence, the potential energy becomes 0.

Answer:

The "solid force"? ... The direction of the force always seems to be coming out of the solid surface. A direction which is perpendicular to the plane of a surface is said to be normal. The force that a solid surface exerts on anything in the normal direction is called the normal force.

Answer:

The force that must be applied to the chain in order for the chain to have the given acceleration is approximately 694.2 N

Explanation:

The given restive force, [tex]F_f[/tex] = 130 N

The mass of the wheel, m = 1.70 kg

The diameter of the wheel, D = 50.0 cm

∴ The radius of the wheel, R = 50.0 cm/2 = 25.0 cm = 0.25 m

The diameter of the sprocket over which the chain passes, d = 8.75 cm

The radius of the sprocket over which the chain passes, r = 8.75 cm/2 = 4.375 cm = 0.04375 m

The angular acceleration, α = 3.50 rad/s²

Torque, τ = I·α

Where;

I = The moment of inertia = m·R²·α

The net torque = The applied torque - The friction torque

Therefore, we get;

I × α = m × R² × α = F × r - [tex]F_f[/tex] × R

1.70 kg × (0.25 m)² × 3.50 rad/s² = F × 0.04375 m - 120 N × 0.25 m

F = (1.70 kg × (0.25 m)² × 3.50 rad/s² +  120 N × 0.25 m)/(0.04375 m) = 694.214286 N

The force that must be applied to the chain in order for the chain to have the given acceleration, F ≈ 694.2 N

Coding is all about logic, since I do not have the actual problem from the website I will guide you on how to solve this.

Since you need to go a certain direction you will need to indicate to the character which direction to go. Next, we need to prevent the player from travelling through a wall, we can accomplish this using an IF/ELSE statement. IF the next block in that direction is a wall then do not move forward, ELSE move forward. We would call this statement every time the player tries to move in any direction. Finally, once we reach the lettuce we need to continue picking it until there is no more. To do this we use a While loop, that checks to see if there is any more lettuce, if there is it will run the code to pick up lettuce, if there is NO more then the While loop will exit. That would be the entire code.

TRUE

Answer:

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it

Answer: 0.7

Explanation:

A fisherman sees 7 wave crests go by in 10 s, with wavelength (λ) ia 2.43 m has the frequency of the wave is 0.7 hertz.

A wave is defined as the propagation of distrubance from one place to another. It can carries energy when it propagates into the medium without the net movement of the particles.

It refers to the variations or flow of energy without the transfer of mass of particles or matter. The waves can be visible or invisible. Light and sound are travel in the form of waves.

In waves, the wavelength, frequency, wavespeed and time period can be identified. Frequency refers to the number of oscillations takes place per unit time. It is measured in hertz (Hz).

Wavelength(λ) defines the distance travelled by the wave in a particular time in one vibration. It is also defined as the spatial period of the wave. It can be obtained by taking ratio between wavespeed and frequency. The unit of wavelenght is meter(m).

Wavespeed of the wave equals the wavelength and frequency. It defines the distance travelled/ number of meter covered by given time. Wavespeed (v) = wavelength (λ) / frequency (f). Its unit is m/s.

Time period is inversely proportional to the frequency (f). The time taken by the wave to complete its one oscillation is called time period. Time period = 1 / f . Its unit is seconds (s).

From the given,

time = 10 secs

no of waves = 7

wavelength = 2.43 m

To obtain frequency from the givens, the formula for frequency is:

frequency = no.of.cycles of waves / time taken

                 = 7 / 10

          f     = 0.7 hertz.

Hence, the frequency of the wave is 0.7 Hz for 7 waves and given time 10 s.

Answer:

Kinetic energy is energy possessed by a body by virtue of its movement. Potential energy is the energy possessed by a body by virtue of its position or state. While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment.

Both energies are related to motion.

Answer:

F = 987600 N

Explanation:

Force Equation

F=ma

Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.

Solve

F = m * a

F = 100 kg * 9876 m/s2

F = 987600 N

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

Answer:

D. The tea loses heat to the spoon causing the spoon to become warmer

Explanation:

When the silver spoon at a lower temperature than the tea, is added to the tea, it makes thermal contact. Hence, the heat transfer starts between the two until the equilibrium is reached. We know that the heat transfer takes place from the body with a higher temperature to a body with a lower temperature. As a result, the body with higher temperature loses heat and its temperature lowers down. While the body with a lower temperature gains heat and its temperature rises.

Therefore, the correct option is:

D. The tea loses heat to the spoon causing the spoon to become warmer

You have control over how fast you go up the stairs.

You also have control over how far up the stairs you go.

Therefore the answer is

If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.

Answer:

Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.

C. Distance 90 feet Displacement 0 feet

Answer:

1321 N/C

Explanation:

From the question,

Electric Field (E) = Electric Force(F)/Electric Charge(q)

E = F/q............ Equation 1

Given: F = 7.4 μN = 7.4×10⁻⁶ N, q = 5.6 nC = 5.6×10⁻⁹ C

Substitute these value into equation 1

E = ( 7.4×10⁻⁶)/(5.6×10⁻⁹)

E = 1.321×10³ N/C

E = 1321 N/C

Hence the magnitude of the electric field at that location is 1321 N/C
