Answer:
Explanation:
unbalance force can be defined as the force that makes object slow up or down, in order words unbalanced force can be defined as anything that can alter the state of motion of an object.
an example of an unbalanced force is likened to a situation of someone inside a lift going for a meeting at the top floor, the force which propels the lift upward is unbalanced, because it is greater than the force acting on the lift.
In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.
<h3>What is freezing?</h3>
It is a physical change in which liquids give off heat to form solids.
We have 210.0 g of water at 0°C. We can calculate the amount of heat given off when it freezes into ice using the following expression.
Q = ΔH°fus × m
Q = 0.334 kJ/g × 210.0 g = 70.1 kJ
where,
- Q is the heat released.
- ΔH°fus is the latent heat of fusion.
- m is the mass.
In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.

<em>The velocity vector of an object with a centripetal acceleration is never tangent to the circular path is False.</em>
Answer: <em>False</em>
Explanation:
Centripetal acceleration is a feature of objects in uniform circular motion. In that case velocity is along the tangent drawn to the circular path. For an object to be called accelerating its velocity should be variable but speed needn’t.
Even when the speed is constant an object can be accelerating. The direction of velocity of an object in uniform circular motion keeps changing continuously. This change in velocity in uniform circular motion is equal to the centripetal acceleration.
Answer:
I hypothesis that the motion involving the balls in the experiment were moving to create data.

I hope this helps!
Answer:
4.78 x 10^-17 m
Explanation:
E = 26 GeV
First convert GeV into J
1 GeV = 1.6 x 10^-10 J
E = 26 x 1.6 x 10^-10 = 41.6 x 10^-10 J
Use the formula for energy
E = h c / λ
Where, h is the Plank's constant and λ be the wavelength and c be the velocity of light.
λ = h c / E
λ = ( 6.63 x 10^-34 x 3 x 10^8) / (41.6 x 10^-10)
λ = 4.78 x 10^-17 m
