The formula for this equation is:
change in velocity/time taken = acceleration
7/3 = 2.3...
so the answer is 2.3 m/s
(I am not positive with the answer but I do know that is the formula for the equation)
Consider that when heigt is 35 meters, the velocity is zero. The you can use the formula for free fall with initial velocity zero
Vf = √(2gh) = √(2*9.8m/s^2 * 35m) = √686m^2/s^2 = 26.2 m/s
Assumption: 35 m is the maximum height from the ground, else, if the maximum heigth from the ground is 35 m + 1 m = 36 m, the numbers are:
Vf = √(2*9.8m/s^2*36m) = 26.6 m/s
Answer:
(a) 
(b) 1.3927 Nm
Explanation:
We have given that radius 
Current i = 2.34 A
Angle 
Uniform magnetic field B = 12.6 T
Area is given by 
(A) We know that magnetic dipole moment is given by 
, here i is current and A is area
So magnetic moment 
(b) We know that torque is given by
So torque experienced by coil will be 
C) benjamin franklin: kite experiment, lightning rod
Explanation:
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.
If a gas is heated up, its particles move around more quickly. They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts.
This is why balloons and tyyres burst if you blow them up too much. It's also why deodorant spray cans carry warning signs to tell you not to leave them in the sunshine. If they get too hot they explode.
