Answer: As you slide down the plastic slide, electrons move from the plastic to you. Now you have extra electrons. Touch another person or an object (anything that isn't negatively charged by extra electrons) and ZAP!

technically, since no one is sliding down the other side of the slide there aren't any extra electrons being made, so you can't really get shocked.

Answer:

u = 7.74 m/s and t = 1.82 s

Explanation:

Given that,

Harold threw a baseball 3 meters.

Harold is 2 meters tall.

The vertical distance = 3m

The final velocity at the maximum height is  0.

Let u is the initial velocity of the baseball. Using the first equation of motion to find it as follows :

[tex]v^2-u^2=2as[/tex]

Here, a = -g

[tex]v^2-u^2=-2gs\\\\u=\sqrt{2gs} \\\\=\sqrt{2\times 10\times 3} \\\\=7.74\ m/s[/tex]

He has thrown it with the speed of 7.74 m/s

Let t is the time taken by the ball to fall on the ground.

Harold is 2 meters tall. Using second equation of motion to find it.

u = -7.74 (as downward direction is taken as positive)

[tex]s=ut+\dfrac{1}{2}at^2\\\\2=-7.74t+5t^2\\\\t=1.82\ s[/tex]

Hence, this is the required solution.

Answer:

the answer is B

Explanation:

because i had this question in 8th grade

Answer:

1. The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.

2. The temperature at which a substance changes from the liq- uid state to the solid state is called the freezing point. The freez- ing point of the liquid state of a substance is the same temperature as the melting point of the solid state. For example, solid water melts at 0°C and liquid water freezes at 0°C.

3. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. 4. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

Answer:

It is A, B, and C

Explanation:

I just took the test!

The three characteristics mechanical waves and electromagnetic waves share are:

A. The waves begin with a disturbance.

B. The waves transfer energy from its source.

C. The waves and their energy move outward from the source.

       Usually, waves transfer energy from one place to another. Mechanical waves transfers via matter where as electromagnetic waves transfers via light. Both mechanical waves and electromagnet (light) waves measured through amplitude, wavelength, frequency and both will get transmitted, refracted, reflected, absorbed, diffracted when they react with matter. Both the electromagnetic waves and mechanical waves are transverse in nature but the mechanical waves can also be in longitudinal.

So, many characteristics were similar for mechanical waves and electromagnetic waves.

Hence, Option A, B, C are the three characteristics.

Answer:

a= g = - 9.81 m/s2.

The following equations will be helpful:

a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad

When you substitute the specific acceleration due to gravity (g), the equations are as follows:

g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd

If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:

g = vf /t d = 1/2 gt2 vf2 = 2gd

The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

Answer:

a. v(1.8) = -3.14 m/s

b. [tex]v_{max} = 3.925\ m/s[/tex]

c. [tex]a_{max} = 3.08\ m/s^2[/tex]

Explanation:

a.

The speed of a particle executing simple harmonic motion is given by the following equation:

[tex]v(t) = -A \omega \ Sin(\omega t)[/tex]

where,

v = velocity = ?

A = Amplitude = 5 m

ω = angular frequency = [tex]\frac{2\pi}{Time Period} = \frac{2\pi}{8\ s}[/tex] = 0.785 s

t = time

First we find time at 3 m by using equation for displacement:

[tex]x = 3\ m = ACos(\omega t)\\Cos((0.785 rad/s)(t)) = \frac{3\ m}{5\ m}\\t(0.785\ rad/s) = Cos^{-1} (0.6)\\t = \frac{0.927\ rad}{0.785\ rad/s}\\t = 1.18 s[/tex]

Therefore,

[tex]v(1.8) = velocity at 3\ m = -A\omega Sin(\omega t)\\v(1.8) = -(5\ m)(0.785\ rad/s)Sin((0.785\ rad/s)(1.18\ s))\\[/tex]

v(1.8) = -3.14 m/s

c.

The maximum speed is given as:

[tex]v_{max} = A\omega\\v_{max} = (5\ m)(0.785\ rad/s)\\[/tex]

[tex]v_{max} = 3.925\ m/s[/tex]

The maximum acceleration is given as:

[tex]a_{max} = A\omega^2\\v_{max} = (5\ m)(0.785\ rad/s)^2\\[/tex]

[tex]a_{max} = 3.08\ m/s^2[/tex]

Answer:

48 seconds

Explanation:

Since S=d/t, plug in the known values and solve

0.25m/s=12m/t

0.25m/s*t=12m

t=12m/0.25m/s

t=48 seconds

Answer:500

Explanation:

If two forces are acting on an object in the same  direction, then they will add up and the net force will be the sum of their magnitudes. Thus, the net force on refrigerator is 500 N.

Force is an external agent acting on a body to deform it or to change it form the state of rest or motion. There are various kinds of forces, such as gravitational force, frictional force, magnetic force etc.

If two forces are acting on a on an object in the same  direction, then they will add up and the net force will be the sum of their magnitudes. If they are acting from the opposite directions, they will cancel each other in magnitude and and the net force will be the subtracted value.

Here, both Allison and fred pulls the refrigerator from the same direction and the net force is the sum of  forces by each person. Therefore, the net force here is 300 + 200 = 500 N.
