1) C. velocity
Acceleration is defined as the rate of change of velocity per unit time. In formulas:
where
is the change in velocity
is the time interval
Therefore, the correct answer is C. velocity.
2) A. 9.8m/s/s
Earth's gravity is a force, so it produces an acceleration on every object with mass located on the Earth's surface. This acceleration can be calculated, as it is given by the formula
where
is the gravitational constant
is the Earth's mass
is the Earth's radius
By substituting these numbers into the formula, one can find that the acceleration due to Earth's gravity is 
.
Explanation:
A. answer is the correct answer
Answer:
For other liquids, solidification when the temperature drops includes the lowering of kinetic energy, which allows molecules to pack more tightly and makes the solid denser than its liquid form. Because ice is less dense than water, it is able to float at the surface of water.
Explanation:
have a great day:)
Potential energy = mass x acceleration due to gravity x height
= 2.5 x 9.8 x 2.2
= 53.9 J.
Hope this helps!
it is easier to thrust a magnet into a wire coil with one loop than one with four loops Because with four loops it becomes more difficult to push the magnet in.
<h3>What is a magnetic field?</h3>
It is the type of field where the magnetic force is obtained. The magnetic force is obtained it is the field felt around a moving electric charge.
The quantity of turns or loops in a coil directly relates to the intensity of the magnetic field within the coil.
As a result, the magnetic field strength has increased fourfold when there are four loops instead of one, making it more difficult to push the magnet in.
A single-looped wire coil is simpler to insert a magnet into than one with four loops. because inserting the magnet gets more challenging when there are four loops.
