Answer:
Option D
Explanation:
<u><em>Given:</em></u>
Mass = m = 110 kg
Acceleration due to gravity = g = 9.8 m/s
<u><em>Required:</em></u>
Weight = W = ?
<u><em>Formula</em></u>
W = mg
<u><em>Solution:</em></u>
W = (110)(9.8)
W = 1078 N
Answer:
Explanation:
Given
Mass = 10kg
Velocity = 2m/s
Required
Calculate the momentum of the man
Momentum is calculated as thus
or
So; to solve this question; we simply substitute 10kg for mass and 2m/s for velocity in the above formula;
The formula becomes
Hence, the momentum of the man is
Answer:
The value is
Explanation:
From the question we are told that
The time taken to travel to the planet from earth is
The time to be spent on the ship is
Generally speed can be obtained using the mathematical relation represented below
The 2 in the equation show that the trip is a round trip i.e going and coming back
=>
=>
The buoyant force must be greater than water.
The sun emits electromagnetic radiation so I think they are electromagnetic waves.
