Answer:
okay sooo the weight is: 294 n
the normal force is 286 n
the acceleration is: -0.38 m/s²
Answer:
Explanation:
Ohm's law:
V = IR
Given V = 120 V and R = 15 Ω:
120 V = I (15 Ω)
I = 8 A
Answer:
It takes 1 second to drop 26.4 meters, for acceleration due to gravity, the acceleration would double from the meters and would be 52.8 m/s^2.
Is there more information above question 4?
The answer is 2.49 x 10^5 KJ. This was obtained (1) use the formula for specific heat to achieve Q or heat then (2) get the energy to melt the copper lastly (3) Subtract both work and the total energy required to completely melt the copper bar is achieved.
It is due to the plurality of forces enacted on them. For example a bullet, if fired from a firearm, will move forward due to force from the gun, will slow down due to drag from air resistance, and will move downwards due to gravitational force. All these forces culminate in a parabolic (curved) path.
