Answer: The correct answer is option (A).

Explanation:

Initial velocity of the balloon = 0 m/s

let the distance covered by the balloon from roof to the ground= h

Time taken by the balloon to reach the ground = t = 2.5 seconds

Acceleration due to  gravity = g =9.8 m/s^2

Using confuse equation of the motion:

h=ut+\frac{1}{2}gt^2

h=0 m/s\times 2.5 s+\frac{1}{2}\times9.8 m/s^2\times (2.5 s)^2=30.625 m\approx 30.6 m

Hence, the correct answer is option (A).

A 238 N force is applied to a 25 kg object. What is the object's acceleration?
Ganezh [65]

Answer:

<h2>9.52 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{238}{25}  \\  = 9.52

We have the final answer as

<h3>9.52 m/s²</h3>

Hope this helps you

When fat comes in contact with sodium hydroxide, it produces soap and glycerin. Determine whether this is a physical change or a
DochEvi [55]

A quick, easy way to decide whether there was a chemical change

is to look and see whether there are NEW substances after the

event, that weren't there when it started.


This particular scenario started out with fat and sodium hydroxide (lye).

And then, suddenly, POOF ! Soap and glycerin showed up. Where did

THOSE come from ? They came from the molecules in fat and lye,

getting broken up and recombined to make different substances.

THAT's exactly a chemical change.

According to Newton’s law of universal gravitation, as the mass or one or both bodies increases, what happens to the force of at
wel

Answer:

force increases

Explanation:

Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.

According to Newton’s law of universal gravitation, as the mass or one or both bodies increases, the force of attraction between the bodies increases.

Mathematically, this is given by the Newton's Second Law of Motion;

Force = mass * acceleration.
