Answer:
Explanation:
Energy stored in a capacitor is given by the expression
E = Q² / 2C , where Q is charge on it and C is its capacitance . As we put dielectric slab between the plates , capacitance increases , Due to it energy decreases as capacitance form the denominator in the formula above and Q is constant .
Hence energy decreases.
Graduated cylinders have numbers on the side that help you measure volume
Let the distance from the ground to where the rocket clears the wall be x.
x/27.0 = tan 60° , x = 27.0 × tan 60° = 46.8m (rounded off to 1 decimal value)
The rocket clears the wall by 46.8m - 11.0m = 35.8m
<u>How far the rocket lands:</u>
Distance =Velocity × time
Velocity = 75.0m/s
Time = ?
Time due to free fall = Velocity ÷ Acceleration due to gravity(9.8m/s²) = 75.0/9.8 = 7.7seconds (rounded off to 1 decimal value)
Distance = Velocity × Time = 75.0m/s × 7.7s = 577.5m
<u>Final velocity as the rocket hits the ground:</u>
Velocity due to free fall = Acceleration due to free fall × Time = 9.8m/s² × 7.7s = 75.5m/s (rounded off to 1 decimal value).
Answer:
1. A and C are balanced forces as all the forces get cancelled by the opposite and equal force.
2. B and D as in B the Net force is 5N to the right and in D the Net force is 20N to the right.
3. This would be all the unbalance forces which are B and D
4. B would be moving 5N to the right and D would move 20N to the right.
