What is the velocity of an object that has been in free fall for 0.10 s?

Physics

Agata [3.3K]3 years ago
7 0
Formula for calculating the velocity of an object that has been in free fall:
v = g * t, where g = 9.81 m/s² ( acceleration of the gravity ) and t stays for time, t = 0.10 s.
v = 9.81 m/s² * 0.10 s = 0.981 m / s  ( or 3.53 km / h ).
Answer: The velocity of an object is 0.981 m / s.

Answer:

A. evaporation

Explanation:

Evaporation is a surface phenomenon as the molecules of the surface gets sufficient energy to overcome the force of attraction which will help in converting to the vapor phase.

Why is water considered to be a complex compound
DedPeter [7]
HEY THERE !!

\huge{COMPOUND:-}
Compounds contain two or more different elements. 


Water is a molecule because it contains molecular bonds . Water is also a compound  because it is made from more than one kind of element. (oxygen and hydrogen).

So If you like, you can say that water is a molecular compound.

HOPE IT HELPED YOU.

Imagine you are holding an apple. a. Does this apple have energy? How do you know? b. How could you increase the potential energ
Len [333]
A).  The apple has thermal energy, because its temperature is higher
than absolute zero.
It also has chemical energy, because if I eat it, I get a burst of energy
and I become ambitious for a while.
It also has gravitational potential energy, because if I drop it on my foot,
it could bruise one of my piggies.

b).  I could increase its potential energy by lifting it higher, like over my head.

c).  As long as I'm just holding the apple, it doesn't have any kinetic energy. 
I could give it some kinetic energy by throwing it.
Or I could just drop it, and let gravity give it kinetic energy.

Describe the initial horizontal and vertical velocity of a horizontally launched projectile on Earth, as well as what happens to
Jobisdone [24]

Answer:

Explained below

Explanation:

To explain this, let's consider a tennis ball being launched from the top of a very high building.

Now, if the tennis ball is launched horizontally without any upward angle but with an initial velocity of 10 m/s. In this motion, If there is no gravity, the tennis ball would continue in motion at that same speed of 10 m/s in the horizontal direction. However, in reality, gravity causes the tennis ball to accelerate downwards at a rate of 9.8 m/s for every second. This implies that the vertical velocity component is changing at the rate of 9.8 m/s every second.

Thus, after 1 second, horizontal velocity component will remain 10 m/s and vertical component will be 9.8 m/s × 1 = 9.8 m/s downwards.

Also, after 2 seconds, the vertical velocity component will remain 10 m/s, however the vertical component will now be 9.8 × 2 = 19.6 m/s downwards.

Same procedure is repeated as t increases by 1 second.
