M=20 kg
g on earth=9.8m sec^-1
F=m*a
F=20*9.8
F=196N

Answer:

D. 196 N

Explanation:

The force of gravity acting on an object located at the Earth's surface is given by:

F=mg

where

m is the mass of the object

g is the acceleration due to gravity

In this problem:

- m=20 kg is the mass of the object

- g = 9.81 m/s^2 is the acceleration due to gravity at Earth's surface

Substituting these data into the formula, we get

F=(20 kg)(9.81 m/s^2)=196.2 N \sim 196 N

according to newton's second law of motion of the net force acting on the object increases while the mass of the object remains
Licemer1 [7]

Answer:

The Acceleration will increase

Explanation:

Newton's Second Law of motion: It states that the rate of change of momentum is directly proportional to the applied force and takes places along the direction of the force.

It can be expressed mathematically as,

F ∝ m(v-u)/t

Where (v-u)/t = a

F  = kma.

F = force, m = mass of the body, a = acceleration, k = constant of proportionality which tend to unity for a unit force, a unit mass, and a unit acceleration.

Therefore,

F = ma.

From the equation above,

If the net force acting on a body increase, while the mass of the body remains constant, the acceleration will also increase.

What molecular geometry would be expected for f2 and hf?
Kaylis [27]
The molecular geometry of both F2 and HF is linear.

There are only two atoms which are covalently bonded and thus, the bonding scheme with the atoms looks like this;

F --- F

H---F

So, both are linear.

True or False:
viva [34]

Answer:

True. The object's location is based off of the reference point, so by moving the reference point, you move the object's location.
