Answer:
<h2>9.375Nm</h2>
Explanation:
The formula for calculating torque τ = Frsin∅ where;
F = applied force (in newton)
r = radius (in metres)
∅ = angle that the force made with the bar.
Given F= 25N, r = 0.75m and ∅ = 30°
torque on the bar τ = 25*0.75*sin30°
τ = 25*0.75*0.5
τ = 9.375Nm
The torque on the bar is 9.375Nm
Answer:upper right hand side i think
Explanation:
Explanation:
A distance-versus-time graph gives the distance an object has traveled after a given time.
In a distance-versus-time graph the slope represents the the speed of the object because
is

And how steep the slope of the distance-versus-time graph is tells us how fast an object is moving; steeper the slope greater the speed. For example, a graph with slope 10 represents a greater speed than a graph with slope 2.
So the steepness of the slope of the distance-versus-time is the speed of the object, and greater the slope greater is the speed.
