Marat540 [252]2 years ago
8 0

Answer:

f = 15 N

Explanation:

It is given that, when you push with a horizontal 15-N force on a book that slides at constant  velocity, a frictional force also acts on it. Frictional force is an opposing force. The magnitude of applied force and frictional forces are same. So, the force of friction on the book is equal to 15 N.

Answer:

Given: V=12 V

            I=2.5 mA

Let the resistance be R

By Ohm's Law, 

V=IR

12=2.5×10−3R

R=4.8×103 Ω

A multi-dimensional being reaches down to Earth and pulls you out of the universe. You are then thrown back into the universe at
Shkiper50 [21]

You are in an early universe.

In the study of the evolution of the universe, it has been determined before Plank time (before the big bang and right after it), the early universe had the following characteristics:

  • There was only one single force acting over all that existed.
  • The early universe was very hot and dense because all matter had contracted before the big bang.
  • Space and time were wrapped.

These characteristics match the ones described, based on this, we can conclude you are in an early universe.

13. Suppose that the strength of the electric field about an isolated point charge has a certain value at a distance of 1 m. How
VMariaS [17]

Answer: E/4 ( one - fourth of it electric field)

Explanation:

The electric field of a point charge is given below as

E =kq/r²

E = electric field,

K = electric constant

q = magnitude of electric charge

r = distance between point charge and electric field.

It can be seen that only E and r are the only variable here and also, E is inversely proportional to r²

Which implies that

E = k/r² , k = E × r²

E1 ×(r1)² = E2 × (r2)²

Let E1 = E, r1 =1, r2 = 2 and E2 =?

Let us substitute the parameters

E × 1 = E2 × 2²

E × 1 = E2 × 4

E = E2 × 4

E2 = E/4

Which implies that the electric field at the second distance (r =4) is one fourth of the initial electric field.
