Answer:
option B
Explanation:
Radius of new planet,R' = 2R
Mass of the earth, M' = 2 M
R and M is the Radius and Mass of the earth.
Weight of the person on earth = 500 N
Weight of the person in the new planet = ?
We know acceleration due to gravity is calculated by using formula
now, acceleration due to gravity on the new planet
here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.
Weight on the new plane is equal to = 250 N
correct answer is option B
Answer:
1) 0.67HP
2)
Explanation:
1)In order to solve the problem we use the conversion between HP and Watts:
1HP=746Watts
So:
500W*(1HP/746W)=0.67HP
2)The power delivered is equal to the ideal power multiplied the motor's efficiency:
The main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system
<h3>What is ozone depletion?</h3>
Ozone depletion is the gradual thinning of the ozone layer in the upper atmosphere as a result of the relelase of chemical compounds or gases.
Ozone layer helps prevent the Earth surface against incoming ultraviolet radiations that could cause damage to our environment.
Therefore, the main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system
