Answer:
B. Resistivity
Explanation:
Resistance offered by a substance of unit area per unit length.
Answer:
energy is equal to 1000 J
Explanation:
When the jumper is in the tent, he has a given height, this height gives him a gravitational potential energy, which forms his initial mechanical energy of 1000 J. After jumping, this energy is converted into elastic energy of the rope plus a remainder of potential energy gravitational, it does not reach the ground, but as the friction is negligible the total mechanical energy is conserved, therefore its energy is equal to 1000 J
This is a case of energy transformation, but the total value of mechanical energy does not change
Answer:
2m/s/s
Explanation:
The formula goes- F=MA
F-Force M-Mass & A-Acceleration
We need to rearrange this formula to find the acceleration-
A=F/M
All we need to do now is substitute the values in
A=2000N/1000kg
A=2m/s^2
In the given option the last option (2m/s/s) would be the ans, as it's the same as 2m/s^2
So ya, I guess that's all
Answer:
m = 14*26 = 364
Explanation:
overall magnification is given as m

mo magnification of objective lens
me magnification of EYE lens
where mo is given as

and me as

d is distant of distinct vision = 25.0 cm for normal eye
fe = focal length of eye piece
focal length of objective lense is 0.140 cm
we know that








m = 14*26 = 364
