Answer:
In a second class lever, the load is located between the effort and the fulcrum. If the load is closer to the fulcrum than the effort, then less effort will be required to move the load. If the load is closer to the effort than the fulcrum, then more effort will be required to move the load.
Explanation:
from what i learned, if its farther away from the load, its easier to lift, like a wheel barrel
Answer:
v²=u²+2as
0²=(7.8)²+2×9.8×s
s=60.84/19.6=3.1m she travel 3 .1m high.
weight=m×g=
Answer:
30.30 m/s
Explanation:
mass of car, m = 1501 kg
angle of banking, θ = 25°
radius, r = 201 m
Let the speed is v.
The relation for the speed is given by
v = 30.30 m/s
Explanation:
Carbon-14 is normally used to date living organisms (all living things we know today contain mostly carbon). It can be used for samples up to about 60000 years old. Carbon-12 is the non-radioactive form that we encounter daily. Relative dating determines dates relative to each other, such as ordering of period or events.
Uranium 235 dating can determine date samples a million years old and up, so is more suited for rocks.
We have: v = d/t
From the expression, we conclude speed is indirectly proportional to speed.
So, the car which will take longer time must have the smallest speed. Among all the options Car C has the smallest speed. So, it would be your answer.
In short, Your Answer would be Option C) Car C will take longer time than any other.
Hope this helps!
