<span>force applied causes movement of an object in the same direction as the applied force.</span>
Answer:
Two times as much
Explanation:
The equation for gravitational force is: Fg = GMm/r^2 with G being the universal gravitational constant.
So to make things easier we'll set r equal to 1 since it's a constant as well as G.
Then we're left with Fg=Mm with M being the mass of the sun and m being the mass of the earth.
So if m is constant and supposedly equals 1 then Fg=M so Fg is proportional to M therefore if M doubles then Fg doubles.
Answer:
v₁
Explanation:
A crew member is walking on a tugboat that is pulling a barge. The tugboat is moving at a constant speed upstream in a river that has a constant downstream current. The velocity of the crew member with respect to the tugboat is v₁. What is the velocity of the crew member with respect to the barge?
velocity is the change in displacement per time.
the velocity of the crew member with respect to the barge is v₁ since the barge is moving in the velocity of tugboat
:Answer:
a. the initial angular velocity = 166.5rad/s
b. t= 135.7seconds
Explanation:
a. v = rw
angular velocity for 2870 rev, w = (2πN)/60 =2*3.142*2870rev)/60 =300.5rad/sec
w₁-w₂ = 300.5 - 133= 166.5rad/s
the initial angular velocity = 166.5rad/s
acceleration = change in velocity / time
b. 1 revolution = 2π
1 rad = 0.159rev
? = 2870 rev
=2870*1)/0.159 = 18050.3rad
the final angular speed = rev/time = rad/time
133 rad/s = 18050.3/t
133t = 18050.3
t= 135.7seconds
