g A mouse is sitting on top of the block in the previous question. As a reminder, the block is sliding down a ramp at a constant

speed, and the ramp is at an angle. How many forces from our list of forces in this class (ignoring air drag) are acting on the mouse at this time?

4 0

Answer:

The number of forces that are acting on the mouse will be three (Normal force, friction force and force of the mouse´s weight)

Explanation:

The number of forces that are acting on the mouse will be three. the first is the normal force acting on the midpoint of the mouse, this force is directed upward, the other is the force between the block and the bottom of the mouse, which is the friction force, and the third is the force of the mouse´s weight, which is defined as the multiplication of mass by gravity.

An object has a mass of 20 kg and is placed 2 m above the ground. What is its gravitational potential energy? (PEg)
Deffense [45]

Answer:

<h2>392 J</h2>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

PE = 20 × 9.8 × 2

We have the final answer as

<h3>392 J</h3>

Hope this helps you

A positive charge of 18nC is evenly distributed along a straight rod of length 4.0 m that is bent into a circular arc with a rad
sergey [27]

Explanation:

Formula for angle subtended at the center of the circular arc is as follows.

           \theta = \frac{S}{r}

where,   S = length of the rod

              r = radius

Putting the given values into the above formula as follows.      

                \theta = \frac{S}{r}

                             = \frac{4}{2}

                             = 2 radians (\frac{180^{o}}{\pi})

                             = 114.64^{o}

Now, we will calculate the charge density as follows.

                 \lambda = \frac{Q}{L}

                            = \frac{18 \times 10^{-9} C}{4 m}

                            = 4.5 \times 10^{-9} C/m

Now, at the center of arc we will calculate the electric field as follows.

                 E = \frac{2k \lambda Sin (\frac{\theta}{2})}{r}

                     = \frac{2(9 \times 10^{9} Nm^{2}/C^{2})(4.5 \times 10^{-9}) Sin (\frac{114.64^{o}}{2})}{2 m}

                      = 34.08 N/C

Thus, we can conclude that the magnitude of the electric eld at the center of curvature of the arc is 34.08 N/C.

What is the potential energy of a puppy that weighs 18 N istting in a high chair 2 m high?
kykrilka [37]

Answer:

Potential energy =mass* acceleration due to gravity * height

mass*acceleration due to gravity =weight

hence potential energy of the puppy= weight * height

=18*2

=36 joule
