Answer:
a) 7.848 m/s
b) 3.156 m
Explanation:
t = Time taken
u = Initial velocity = 1.75 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
His highest height above the board is 0.156 m
b) Total height he would fall is 3+0.156 = 3.156 m
He is in the air for 0.8+0.18 = 0.98 seconds
a) His velocity when he hits the water is 7.848 m/s
Answer:
6 Joules
Explanation:
The change in internal energy must be equal the work done by pushing the handle with a 20 N force a distance of 0.3 meters. That is:
Change in internal energy = Work = 20 * 0.3 J = 6 Joules

Explanation:
Answer:
800W
Explanation:
Given the following data;
Voltage = 230 V
Model = VSO Ha
Power = 800 W
Power is calculated by the multiplication of voltage and current flowing through an electric circuit.
Mathematically, power is given by the formula;
Power = current * voltage
The S.I unit for power is Watts and it is a measure of the energy consumption of an electronic device.
