Answer:
0 N
Explanation:
This is a trick question, the mass of the wrench would be 0 due to it being in space and has no gravitational pull to weight it down. And since acceleration is defined as the rate and change of velocity with no respect of time and the wrench is moving at a constant velocity, that means the velocity is 0. and since F = m*a it would be F = 0 * 0 = 0 N
Answer:
is destroy.
Explanation:
Because it is one of the demerit of a machine
Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)
Answer:-600N
Explanation:
Mass(m)=1000kg
Initial velocity(u)=25m/s
Final velocity(v)=12.5m/s
Time(t)=22 seconds
v=u+axt
12.5=25+ax22
collect like terms
12.5-25=22a
-12.5=22a
Divide both sides by 22
-12.5/22=22a/22
-0.6=a
Acceleration=-0.6
Force=mass x acceleration
Force=1000 x -0.6
Force=-600
Answer:
1.40625 kg-m^2
Explanation:
Supposing we have to calculate rotational moment of inertia
Given:
Mass of the ball m= 2.50 kg
Length of the rod, L= 0.78 m
The system rotates in a horizontal circle about the other end of the rod
The constant angular velocity of the system, ω= 5010 rev/min
The rotational inertia of system is equal to rotational inertia of the the ball about other end of the rod because the rod is mass-less
=1.40625 kg-m^2
m= mass of the ball and L= length of the ball
