Answer:

The impact speed of the cup is 3.83 m/s.

Explanation:

Given that,

Height = 0.75 m

We need to calculate the impact speed of the cup

Using kinetic and potential energy

K.E=P.E

\dfrac{1}{2}mv^2=mgh

Where,

M = mass of the cup

v = velocity of cup

g = acceleration due to gravity

h = height

Put the value into the formula

\dfrac{1}{2}v^2=gh

v=\sqrt{2gh}

v=\sqrt{2\times9.8\times0.75}

v=3.83\ m/s

Hence, The impact speed of the cup is 3.83 m/s.

When the distance between two stars decreases by one-third, the force between them
pashok25 [27]

Answer:

the force will increase by a factor 2.25

Explanation:

The gravitational force between the two stars is given by:

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1, m2 are the masses of the two stars

r is the distance between the stars

If the distance is decreased by one-third, it means that the new distance is 2/3 of the previous distance

r'=\frac{2}{3}r

So the new force will be

F'=G\frac{m_1 m_2}{(\frac{2}{3}r)^2}=\frac{9}{4} G\frac{m_1 m_2}{r^2}=2.25 F

So, the force will be 2.25 times the previous value.

Light has been measured as traveling at 3×108 m/s in a vacuum. Which of the following also travels at the speed of light, and wh
Art [367]

Radio waves in a vacuum travel at the speed of light because they are a type of electromagnetic radiation like a light has been measured as traveling at 3×10^8 m/s in a vacuum.

Charged particles that are accelerating, like time-varying electric currents, are what produce radio waves. Radio and television signals are transmitted using radio waves, and microwaves used in radar and microwave ovens are also radio waves. Radio waves are emitted by a lot of celestial bodies, including pulsars. High RF exposure levels have the potential to heat biological tissue and raise body temperature. The body's inability to handle or remove the extra heat that could be generated by high RF exposure in humans could result in tissue damage.

Hey, I'm not sure I understand exactly what your assignment is but hopefully this helps . . .

put the other end against the side of the bubls base to light up the light bulb.

This will act as the bulbs conductor, lighting up bc you are making a complete electrical circuit between positive and negative terminals of the battery.

Ok hopefully this helps you out

Violence and in civility between hospital employees can contribute to turnover of.........performers, hinder effective.........,
Dominik [7]
Violence and incivility between hospital employees can contribute to turnover of top performers, hinder effective teamwork, and jeopardize the quality of patient care.This is one of the most important reasons why violence and incivility in hospitals should be avoided at any cost so as to spare the employees and patients from harm and discomfort.

If the mass of an object on earth is 100 kg what is it’s weigjt in earth
Andrej [43]

W = 980N. The weight of an object of 100Kg in the Earth is 980N.

The weight is a measure of the gravitational force acting on an object, the weight is equivalent to the force exerted by a body on a point of support, caused by the action of the local gravitational field on the mass of the body.

it can be defined as the product of mass by the acceleration of gravity, w = mg. Since weight is a force, its unit is the Newton N.

If the mass of an object on earth is 100 kg, then is weight is:

W = (100Kg)(9.8m/s²) = 980N.
