<h3>The colour of the shadow of coloured objects is not same as the colour of the objects</h3>
When an opaque item absorbs all of the light falling from a light source, no light is reflected, and the thing appears black. The color of an object's <u>shadow is independent of its hue; it can be red, yellow, green, or black.</u>
Answer:
Explained
Explanation:
The cheater pipe extends the wrench in radial direction, providing a larger momentum for the force you exert.
For a given force the torque exerted with the cheater pipe is larger.
Mathematically we can write that
τ = r×F and τ'= r'×F
now since r'> r
⇒ F'>F
All are examples of electromagnetic energy except <span>circles forming when a rock drops into a pool. The correct option among all the options that are given in the question is the third option or option "C". The other choices can be negated. I hope that this is the answer that has actually come to your help.</span>
Answer:
the friction force in the reverse direction is 200 *0.4=80 N.
the net forward force acting on the box is therefore
Fnet= 100 - 80 N
= 20 N
acceleration = Fnet / mass
=Fnet *g/(weight)
=20 *9.8/200 = 0.98 m/s^2
Explanation:
D. The table pushes up on the vase with the same amount of force as gravity pulling it down.
