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: 2

Explanation: waves transfer energy without transferring mass

When a wave travels through a medium, the wave transfers: 2. energy, only.

A wave can be defined as a disturbance in a medium that progressively transfers (transports) energy from a source to another location, especially without the transportation of mass (matter).

Generally, the energy of a wave is directly proportional to the square of wave amplitude and the square of its frequency. Thus, a wave transfers only energy without mass when it travels through a medium.

Actually Welcome to the concept of Net force on a body.

We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,

and if the net force on a body is Zero, then it is a balanced force,

here,

Force to left on skier = 50 N

Force to right on skier = 40 N

hence the net force = left force - right force

Net force = 50 - 40 ==> 10 N

hence the Net force is 10 N in the left direction of the skier.

Answer:

Star, hydrogen and energy

Explanation:

A star is a large ball of gas that generates its own energy by fusing hydrogen atoms to make helium. It is held together by its own gravity. This process emits a tremendous amount of energy, and some of the energy is in the form of light.

The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

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

Answer:

A

Explanation:

Answer:

Air resistance is pushing up on the parachute and force of gravity is pulling down so she slows down. This increases friction which slows free fall down. So when the skydiver reaches terminal velocity, the force of gravity is balance by air resistance. But when the forces are balance, there is no acceleration.

Answer:

1. Icy

This is so because the icy surface will be slippery due to ice and water residue on it. Not only the stone, anything that goes on the icy surface is likely to slip. There won't be much friction offered by the surface.

If we talk about the sandy surface, the stone won't go far and will be stopped at the nearest point possible and it's also possible that the stone will settle down in the surface.

The dry and cemented surfaces will cause friction when the stone will be thrown on them, which will stop the stone from going far away.

2. Streamline is the body shape which offers very little resistance to the flow of air.

3. Spring balance is a device used for measuring weight of an object object.

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

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)

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:

C

Explanation:

When the planet in motion should have the same speed so until it should be acted by an outer force. This statement explained the movement of the planets.

Answer:

...............

Explanation:

If an object is placed in front of a plane mirror, the size of the object remains same. This is the property of plane mirror. So the height of the object will be 10cm only.

The image position in the plane mirror is 5 cm.

The ratio of the height of the formed image to the height of the object is used to define the magnification created by the mirror.

Here,

Position of the object, u = -10 cm

Height of the object, h = 10 cm

We know that magnification produced by a plane mirror is 1.

So,

Magnification, m = -v/u

1 = -v/u

Therefore, image distance,

v = -u

v = 5 cm

Hence,

The image position in the plane mirror is 5 cm.

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

Answer:

T = 60°C

Explanation:

We are given;

Mass of water in both cases as 60g.

Thus; m1 = m2 = 60 g

Temperature of first water; T1 = 40°C

Temperature of 2nd water; T2 = 80°C

Let final temperature be T.

To solve for the final temperature, we will use the formula;

(m1 + m2)T = ((m1•T1) + (m2•T2))

(60 + 60)T = ((60 × 40) + (60 × 80))

120T = 7200

T = 7200/120

T = 60°C

Answer:

RT = 54 Ohms

Explanation:

Given the following data;

Resistance = 18 Ohms

Voltage = 12 Volts

To find the equivalent resistance (RT) of the circuit;

For a series connection, the formula is;

RT = R1 + R2 + R3

RT = 18 + 18 + 18

RT = 54 Ohms

Or

RT = 3*R

RT = 3 * 18

RT = 54 Ohms
