First discovery - Herto, Ethopia. 160,000 years ago - 40,000 years earlier than the previous oldest remains homo sapiens.
Answer:
200N
Explanation:
EVERY FORCE IS OPPOSED BY AN EQUAL FORCE, REGARDLESS OF THE WEIGHT OF THE OBJECTS APPLYING THE FORCE.
F = 2820.1 N
Explanation:
Let the (+)x-axis be up along the slope. The component of the weight of the crate along the slope is -mgsin15° (pointing down the slope). The force that keeps the crate from sliding is F. Therefore, we can write Newton's 2nd law along the x-axis as
Fnet = ma = 0 (a = 0 no sliding)
= F - mgsin15°
= 0
or
F = mgsin15°
= (120 kg)(9.8 m/s^2)sin15°
= 2820.1 N
- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And
- Hence force varies directly with acceleration hence weight will be more .
You can tell by making sure that the lights are unplugged and tighten lights then plug it in if I didn't work it's burnt :) hope it works
