Answer: The Answer is B (Sorry if this is late)

Explanation:

I couldn’t find the answer to the question myself then found you, with no answer. So I guessed and failed my third question of the quiz, you were worth the sacrifice though ✨

The pair of waves could overlap to produce a wave with a higher amplitude through interference is that two waves of the same amplitude with crests that are perfectly aligned. Hence, option B is correct.

The maximum deflection or distance made by a point on even a vibrating object or wave relative to its equilibrium location is known as the amplitude in physics. It is equivalent to the length of a vibration path divided in half.

A pendulum's amplitude is therefore equal to the distance that the bob travels when swinging through one side to another. Vibrating sources produce waves, whose amplitude is inversely proportional to the source's amplitude.

The largest deviation of any place on the string out of its place when the line is at rest is used to determine the amplitude of a wave propagation, like the wave on such a plucked string.

Therefore, it concludes that option B is correct.

Answer:

Condensation

Explanation:

Increased pressure is called condensation or compressions because they are regions of high air pressure whilst rarefractions are low air pressure.

Answer:

D. Electromagnetic Induction.

Explanation:

Answer:

1. Divide the weight by speed of the people pushing it to get net force

2. Whether one side of the object is pushing harder or not you will get ur answer, for example if the left side is pushing 3 newtons to the right and the right side pushing 5 newtons to the left, the net force would be 2 newtons of force pushing left and if its an even amount of force then it will be 0

3. If one side of an object pushes harder than the other side, then the object will move in favor of the one who is pushing harder.

4. 200 newtons or 200N

Explanation:

One revolution of the propeller corresponds to a rotation of 2π radians, so that the propeller has an initial angular velocity of

10 rev/s = (10 rev/s) • (2π rad/rev) = 20π rad/s

The propeller thus has an angular velocity ω at time t of

ω = 20π rad/s - (2.0 rad/s²) t

so that at t = 40 s, its angular speed is reduced to

20π rad/s - (2.0 rad/s²) (40 s) = (20π - 80) rad/s

Convert this to a rotation rate by dividing this result by 2π :

(20π - 80) rad/s = ((20π - 80) rad/s) • (1/(2π) rev/rad) ≈ -2.73 rev/s

which would suggest that the propeller has started to turn in the opposite direction at a rate of 2.73 rev/s.

Answer:

When the student slides the rock along the flat surface of the frozen pond, according to Newton's second law of motion, the rock is given an initial velocity of motion. According to Newton's first law of motion, the rock will continue to slide indefinitely unless it is slowed or stopped by an opposite force. According to Newton's third law, the rock experiences a reaction force from the force of friction of the ice which slows it down at a rate given by Newton's second law of motion and the rock is seen to decelerate

Explanation:

Newton's first law of motion, states that an object will remain at rest or maintain a uniform motion in a straight line, unless impressed upon by an external force

Newton's second law states that an applied force is equal to the rate of change of momentum it produces

Newton's third law states action and reaction are equal and opposite.

Explanation:

In a chemical reaction, when mass is conserved , the number of atoms or moles of the reactants must be equal to the number of moles or atoms in the products side.

From the diagram, we should carefully look to see if the number of atoms that makes up the reactants are equal to those on the product side.

 For example:

      A + B → AB

Here, mass is conserved because, on the reactant side, we have 1 atom of A and on the product side we have 1 atom of A

For B, on the reactant side, we have 1 atom of B and on the product side, we have 1 atom of B.

Answer:

Yes, because the number of each type of atom is the same in the products as it is in the reactants.

Answer:

Not accounting for friction, the ball would be falling at 14.0 m/s

Explanation:

Without a coefficient of kinetic friction being provided, we'll have to assume zero friction between the ball and the air.

In that case, the ball's horizontal speed will remain 10 m/s.  To find it's velocity in five seconds then, we just need to take gravity into account.

Let's assume acceleration from gravity is 9.8 m/s².  We can simply multiply that by five seconds to find out how fast it's going at that point:

[tex]9.8\frac{m}{s^2} \times 5s\\= 49 \frac{m}{s}[/tex]

So at five seconds, the ball is moving horizontally at 10 m/s and vertically at 479 m/s.

Now we can simply take the hypotenuse between those two vectors to get the actual speed:

[tex]s = \sqrt{9.8^2 + 10^2}\frac{m}{s}\\s = \sqrt{96.04 + 100}\frac{m}{s}\\s = \sqrt{196.04}\frac{m}{s}\\s = 14.0 \frac{m}{s}\\[/tex]

So lacking air to slow it down, the ball would be going at approximately 14.0 metres per second.

Given that,

Mass of a ball = 300 kg

To find,

The gravitational force acting on the ball.

Solution,

The force acting on the ball is force of gravity. It is equal to the weight of the ball.

W = mg

Substitute the value of m and g in the above formula

W = 300 kg × 10 m/s²

= 3000 N

Therefore, the ball attracts with a force of 3000 N.

Answer:

m = 3.9 [m³]

Explanation:

We must remember that the density of the substance is defined as the relationship between mass over volume. That is expressed in the following equation:

[tex]Ro = m/V[/tex]

where:

Ro = density = 1.3 [kg/m³]

m = mass [kg]

V = volume = 3 [m³]

Now replacing the values.

[tex]m =Ro*V\\m = 1.3*3\\\\m=3.9[m^{3}][/tex]

The electromagnetic waves are determined by the wavelength. Hence, the correct option is D.

Electromagnetic waves are made up of vibrating electric and magnetic fields. The electric and magnetic fields are mutually perpendicular to each other. EM waves are transverse in nature.

Electromagnetic waves can travel through the vacuum in the form of radiation. The EM waves travel with the speed of light 3×10⁸ m/s. EM waves have no mass and charge. These waves can carry energy in space.

The behavior of electromagnetic waves depends on its frequency and wavelength. EM waves are classified into 7 types based on its frequency and wavelength. They are classified from radio waves to  Gamma rays.

Frequency is inversely proportional to wavelength, f = c / λ. Higher frequencies have shorter wavelength and lower frequencies have longer wavelength.

Thus, the wavelength determines the radiation that an electromagnetic waves. Hence, the option D is correct.
