A basketball player pushes down with a force of 34 N on a basketball that is inflated

Physics
1 answer:
zloy xaker [14]3 years ago
8 0

Answer:

2.2 cm

Explanation:

Pressure = force / area

P = F / A

A = F / P

A = 34 N / (9×10⁴ Pa)

A = 0.000378 m²

Area of a circle is:

A = πr²

0.000378 m² = πr²

r = 0.011 m

Diameter is double the radius:

d = 2r

d = 0.022 m

d = 2.2 cm

In most cases, what happens to a liquid when it cools?
erik [133]

Answer:

Option (A) and (F)

Explanation:

As the liquid cools down, it means the temperature decreases the density of the liquid increases in most o the cases.

Now the volume is inversely proportional to the density of substance so density increases.

1. A mass is on a level plane, it has a weight of 20N. What is the coefficient of kinetic friction if an applied force
Arturiano [62]

Answer:

0.4

Explanation:

F-Fr=ma where F is applied force, Fr is friction, m is mass and a is acceleration.

Since the mass is moving with a constant velocity, there's no acceleration hence

F=Fr=\mu N where N is the weight of object and \mu is coefficient of kinetic friction.

F=\mu N and making [tex]\mu the subject

\mu=\frac {F}{N}

Substituting F for 8 N and N for 20 N

\mu=\frac {8}{20}=0.4

Therefore, coefficient of kinetic friction is 0.4

Consider the following equations of motion.
Helen [10]

A) No, the equations presented above are the product of the derivation of position and velocity when the acceleration is constant.

The equations change to polynomial function of the second degree for the description of the acceleration when described as a function of time.

B) Yes, when the acceleration is zero it is concluded that the velocity is constant, therefore they could be used to describe the position as a function of the change in velocity.
