Answer:

\boxed {\boxed {\sf 45 \ Joules}}

Explanation:

Work is the force the causes the movement or displacement of an object. It is the product of force and displacement.

W=Fd

The force is 15 Newtons and the displacement is 3 meters.

  • F= 15 N
  • d= 3 m

Substitute the values into the formula.

W= 15 \ N * 3 \ m

Multiply.

W= 45 \ N*m

1 Newton meter is equal to 1 Joule, so our answer of 45 Newton meters is equal to 45 Joules.

A 9-μC positive point charge is located at the origin and a 6 μC positive point charge is located at x = 0.00 m, y = 1.0 m. Find
sukhopar [10]

Answer:

The coordinates of the point is (0,0.55).

Explanation:

Given that,

First charge q_{1}=9\times10^{-6}\ C at origin

Second charge q_{2}=6\times10^{-6}\ C

Second charge at point P = (0,1)

We assume that,

The net electric field between the charges is zero at mid point.

Using formula of electric field

E=\dfrac{kq}{r^2}

0=\dfrac{k\times9\times10^{-6}}{d^2}+\dfrac{k\times6\times10^{-6}}{(1-d)^2}

\dfrac{(1-d)}{d}=\sqrt{\dfrac{6}{9}}

\dfrac{1}{d}=\dfrac{\sqrt{6}}{3}+1

\dfrac{1}{d}=1.82

d=\dfrac{1}{1.82}

d=0.55\ m

Hence, The coordinates of the point is (0,0.55).

Question 6. B) and c)
maks197457 [2]
The formula for both is v(t) = v0 + a*t

b) v(8) = 0 + 6m/s^2 *8s = 48 m/s

now we know the beginning (2) and end speed (14), but not the time:

c) 14 = 2 + 1.5*t => t = (14-2)/1.5 = 8 seconds
