The force of gravity between two masses increases as they are moved closer together.

option D.

Newton's law of universal gravitation states that the magnitude of the force between two masses is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.

F = GM²/R²

where;

The force of gravity between two masses increases as they are moved closer together. This is because gravity is an attractive force that depends on the distance between the masses.

Answer:

I believe the answer is D: Conductor.

Answer:

W = 0 J

Explanation:

The amount of work done by gas at constant pressure is given by the following formula:

[tex]W = P\Delta V[/tex]

where,

W = Work done by the gas

P = Pressure of the gas

ΔV = Change in the volume of the gas

Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:

[tex]W = P(0\ m^3)\\[/tex]

W = 0 J

Answer:

C

Explanation:

When the frequency of sound changes, we hear a change in pitch. When the frequency of light changes we see a change in color.

Answer:

A and C are 180 deg out of phase (opposite points on a 360 deg wave)

The two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

The two points of a wave is said to be out of phase when they show up or down motion at different times.

If a point on the wave, say (X) is reached to the maximum or minimum point before the other point. Then these two points are said to be out of phase.

Also, when the points are 180 degree apart from each other. Which means if a point is in the crest of the wave and other is on the through.

The diagram below shows a periodic wave. In this diagram,

Hence, the two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

Answer:

Explanation:

Here, we are asked to calculate the average speed in km/minute.

As we know that,

Here,

→ Total distance = 10 km + 10 km

→ Total distance = 20 km

→ Total time = 8 minutes + 2 minutes

→ Total time = 10 minutes

Substitute the values in the formula of average speed,

→ Average speed = Total distance ÷ Total time taken

→ Average speed = 20km ÷ 10 minutes

Answer:

The collision is inelastic

Explanation:

There are two kinds of collision; elastic collision and inelastic collision. In an elastic collision, both momentum and kinetic energy are conserved.

However, in an inelastic collision, kinetic energy is not conserved. So, when the bumper of two cars collide, the cars come to a stop because the collision is inelastic.

R = 18 ohms

Explanation:

Given:

V = 36 volts

I = 2.0 A

R = ?

Use Ohm's law to solve for the resistance:

V = IR

or

R = V/I

= (36 volts)/(2.0 A)

= 18 ohms

Answer:

Let No be initial no of atoms

N = N0 / 2      after 1 half-life

N = N0 / 4     after 2 half-lives

So after 2 half-lives 20 of the 80 atoms remain

Answer:

I = 1.36 x 10⁻⁴ W/m²

Explanation:

The intensity of the sound produced by the Elephant can be calculated by using the following formula:

[tex]I = \frac{P}{A} \\\\[/tex]

where,

I = Intensity of sound = ?

P = power of sound = 0.45 W

A = area = πr² = π(32.5 m)² = 3318.3 m²

Therefore,

[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]

I = 1.36 x 10⁻⁴ W/m²

Answer:

v = 3.84 m/s

Explanation:

In order for the riders to stay pinned against the inside of the drum the frictional force on them must be equal to the centripetal force:

[tex]Centripetal\ Force = Frictional\ Force\\\\\frac{mv^2}{r} = \mu R = \mu W\\\\\frac{mv^2}{r} = \mu mg\\\\\frac{v^2}{r} = \mu g\\\\v = \sqrt{\mu gr}[/tex]

where,

v = minimum speed = ?

g = acceleration due to gravity = 9.81 m/s²

r = radius = 10 m

μ = coefficient of friction = 0.15

Therefore,

[tex]v=\sqrt{(0.15)(9.81\ m/s^2)(10\ m)}[/tex]

v = 3.84 m/s

Answer:

The current is halved

Explanation:

The relationship between the current and the resistance is given by Ohm's Law, as follows:

[tex]V = IR\\I = \frac{V}{R}[/tex]

where,

V = Voltage

I = Current

R = Resistance

Therefore, if we double the resistance:

[tex]I' = \frac{V}{2R}\\\\I' = \frac{1}{2}I[/tex]

Hence the correct option is:

The current is halved

The question is: HELPAAAAAAA A mountain biker moves downhill if he accelerates at 3 m / s2 and takes 15 minutes (900 seconds) down, how far does he travel? HELP ME PLEASE

Answer: The distance travelled by the mountain biker is 2430 km.

Explanation:

Given: Acceleration = [tex]3 m/s^{2}[/tex]

Time = 15 minutes (900 sec)

Displacement = ?

Formula used to calculate the final velocity is as follows.

[tex]v = u + at[/tex]

where,

v = final velocity

u = initial velocity = 0 m/s (here)

t = time

a = acceleration

Substitute the values into above formula as follows.

[tex]v = u + a \times t\\v = 0 + 3 m/s^{2} \times 900 s\\= 2700 m/s[/tex]

The relation between velocity (speed) and distance is as follows.

[tex]Speed = \frac{Distance}{time}\\2700 m/s = \frac{Distance}{900 s}\\Distance = 2430000 m (1 m = 0.001)\\= 2430 km[/tex]

Thus, we can conclude that distance travelled by the mountain biker is 2430 km.

The question is: A tuning fork vibrates at 140 [Hz] and the wave emitted by it propagates with a speed of 340 m / s. Considering the above, it can be correctly stated that the wavelength of the wave emitted by the tuning fork is

Answer: Wavelength of the wave emitted by the tuning fork is 2.43 m.

Explanation:

Given: Frequency = 140 Hz

Speed = 340 m/s

wavelength = ?

Formula used to calculate the wavelength is as follows.

[tex]\lambda = \frac{v}{f}[/tex]

where,

[tex]\lambda[/tex] = wavelength

v = speed

f = frequency

Substitute the values into above formula.

[tex]\lambda = \frac{v}{f}\\= \frac{340 m/s}{140 Hz} (1 Hz = 1 s^{-1})\\= 2.43 m[/tex]

Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.
