Answer:
The acceleration is in 2 D as in between east and south.
Explanation:
mass, m = 50 kg
acceleration, a = 0.25 m/s^2 horizontal
acceleration of elevator, a' = 1 m/s^2 downwards
When a person on the ground the resultant acceleration of the person with respect to the ground is between east and south direction so the path os parabolic in nature. It graph is shown below:
Answer:
Recoil speed,
Explanation:
Given that,
Mass of the comet fragment,
Speed of the comet fragment,
Mass of Callisto,
The collision is completely inelastic. Assuming for this calculation that Callisto's initial momentum is zero. So,
V is recoil speed of Callisto immediately after the collision.
So, the recoil speed of Callisto immediately after the collision is
Answer:
P = 1936 W
Explanation:
Given that,
Voltage, V = 220 V
The resistance of the heater, R = 25 ohms
We need to find the power dissipated in the heater. We know that the power dissipated by the electric appliances is given by :
So, the required power is equal to 1936 W.
