Does energy have mass and take up space?

Answers

Answer 1

Answer: Energy does not have a mass to take up space... because........let's say you shine a light into space the volume of the light beam is zero... And say you shine a torch by a black hole what would happen is gravity would pull the light due to gravity...so NO energy does not have have a mass and take up space....hope it helped

Answer 2

Answer: No its not true energy does have mass and take up space , that is matter so the real answer is matter

Sachi wants to throw a water balloon to knock over a target and win a prize. The target will only fall over if it is hit with a force of 0.035 N. The water balloon has a mass of 11.4 grams. How fast will Sachi have to make the water balloon accelerate to hit the target with enough force and win the prize?Round the answer to the nearest one tenth m/s2.
The water balloon must accelerate m/s2.

Answers

Answer:

3.1 m/s²

Explanation:

Given:

Mass of the balloon (m) = 11.4 g = 0.0114 kg ( 1 kg = 1000 g)

Force acting on the balloon (F) = 0.035 N

Acceleration with which the balloon must be hit (a) = ?

Now, we know that, from Newton's second law, net force acting on an object is equal to the product of its mass and acceleration.

Therefore, framing in equation form, we have:

$F=ma$

Rewriting in terms of acceleration 'a', we get:

$a=(F)/(m)$

Now, substitute the given values and solve for 'a'. This gives,

$a=(0.035\ N)/(0.0114\ kg)\n\na=3.07\approx 3.1\ m/s^2(Nearest\ tenth)$

Therefore, the acceleration of the water balloon to reach the target must be equal to 3.1 m/s².

to remove a tight-fitting jar, megan runs the lid under hot water. What happends to the jar lid when its temperature increases?

Answers

It expands due to heat and makes it easier to open the jar.

Final answer:

Running the lid of a tight-fitting jar under hot water causes it to expand due to thermal expansion, which makes it easier to remove from the jar.

Explanation:

When the lid of a tight-fitting jar is run under hot water, it undergoes thermal expansion due to the increase in temperature. The expansion of the lid causes it to slightly loosen, making it easier to remove from the jar. This happens because metals have higher coefficients of expansion than glass, so the lid expands more than the jar itself.

Which statement about speed and/or velocity is true?Velocity has both speed and direction.

Speed is constant.

Speed has direction and velocity.

Speed is measured over time.

Answers

The statement about speed and/or velocity which is true is: Velocity has both speed and direction.

Velocity refers to the rate of change in displacement (distance) with time. Velocity is a vector quantity and this simply means that, it has both magnitude (speed) and direction.

Mathematically, velocity is given by the formula;

$Velocity = (Distance)/(Time)$
