**Answer:**

**There always is an acceleration in a curvilinear motion, as the velocity vector changes, so always.**

Data is inappropriate

here, we need gauge of the wire i.e., diameter of the wire, so that we calculate the resistance by using the formula

** R = ρl/A **

where R= resistance ; Ω

l = length of wire ; m

A = area of wire ; m²

ρ = resistivity ; Ω-m

But in general ohms law is

V = I R

R = V/I ;

but here we also calculate "R" from length of wire in which the current is flowing.

**Answer:**

D). energy resulting from the attraction between two masses.

**Explanation:**

**Explanation:**

Given that, Tom briskly walks 136 meter East, then turns and walks 100 meters West.

Let East is positive and west is negative.

d₁ = 136 m

d₂ = -100 m

Time, t = 3 minutes = 180 seconds

Average velocity,

**So, Tom's average velocity is 1.32 m/s and it is due west.**

The equation of the energy of a photon is E=h*f.

If we increase the Planck's constant h, the energy would increase.

For example, lets double the value of Planck's constant and name it H:

H=2*h. Now lets put that into the equation for energy that we will call E₂:

E₂=H*f=2*h*f=2*E.

So we can clearly see that E₂=2*E or that if we double Planck's constant, the energy also doubles.
