Imani stirs a cup of hot sencha tea with a cool silver spoon. She notices that the silver spoon becomes warmer. What energy change occurs when the silver spoon is added to the hot cup of sencha tea?

A. The spoon adds its cold to the hot tea

B. The hot tea absorbs the heat from the spoon

C. The cool spoon causes the water to expand thus cooling it

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

Answers

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

2 ways in which the effects of friction can be minimised in the experiment​

Answers

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.

Compare and contrast potential energy and kinetic energy​

Answers

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.

This is vety hard this is level 4 number 10 on code.org plsss help me

Answers

Answer:

Explanation:

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.

How objects on Earth are affected by gravitational force.

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

the soft ballplayer does 9876 joules of work when hitting a ball into center field. Assuming the ball landed 100 meters away from home plate, how much force did the player use to hit the ball?

Answers

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.

During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 130 N to the tire's rim. The mass of the wheel is 1.70 kg and, for the purpose of this problem, assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 50.0 cm. A chain passes over a sprocket that has a diameter of 8.75 cm. In order for the wheel to have an angular acceleration of 3.50 rad/s2, what force, in Newtons, must be applied to the chain

Answers

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
