Answer:
Potential energy on surface of Mars is 6669000 J
Explanation:
As we know that the weight of the climber on the surface of Earth is given as 675 N
So weight of the climber on the Mars is given as
Now we know that gravitational Potential energy is given as
Answer:
1.05 N
Explanation:
K = 0.7 N/m
e = 1.5 m
F = ?
from Hooke's law of elasticity
F = Ke
= 0.7×1.5
= 1.05 N
Answer:
1) Measuring cylinder
2) Top Pan Balance
Explanation:
To find the density of the pebble Nabil should first accurately measure the mass of the pebble using the top pan balance
He should then fill the displacement can till the water reaches the outlet pipe at the to of the cylinder
He should then place the pebble into the cylinder carefully ans allow the water that would start coming out to stop
The volume of water in the displaced cylinder is then measured and the density is found by dividing the mass of the pebble by the volume of water in the measuring cylinder
The only electromagnetic wave that human eye can see or sensitive are those of visible light waves. These are colors representing the color of rainbow(red, orange, yellow, green, blue, and violet). Red, which appears in the outermost shell of the rainbow, has the longest, wavelength, around 620-750 nm
