Answer:

20m

Explanation:

So the formula for PE(Potential Energy) = Mass x Acceleration x Height

So we are given the following

PE = 1960

Mass = 10Kg

Acceleration = 9.8m/s^2 (The reason we have an acceleration is due to gravity)

Height = ?

So to calculate height we will use the same formula

1960 = 10 x 9.8 x h

1960 = 98 x h

1960 = 98h

we divide 98 on both sides

H = 20m

Hope this helped.

m³ is a derived unit because it is a product of three basic units. ( meters*meters*meters)

If the energy transfer diagram created by Ray has error in it, it can be corrected by applying the principle of energy conservation.

Energy diagram is sketch of the energy flow process or energy transfer or energy conversion process.

The law of energy conservation states that, energy can neither be created nor destroyed but can be converted from one form to another.

Thus, if the energy transfer diagram created by Ray has error in it, it can be corrected by applying the principle of energy conservation.

The universe encompasses all of space and time, as well as their contents, which include planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the most widely accepted cosmological explanation for the evolution of the universe. According to this idea, space and time coexisted 13.7870.020 billion years ago, and the cosmos has been expanding since. While the spatial extent of the entire universe is unknown, the observable universe can be measured, which is around 93 billion light-years in diameter at the present time.

Ancient Greek and Indian thinkers devised some of the earliest cosmological conceptions of the world, which were geocentric, with Earth at the centre. More precise astronomical measurements throughout the ages prompted Nicolaus Copernicus to establish the heliocentric hypothesis, which places the Sun at the centre of the Solar System. Issac Newton based his rule of universal gravitation on Copernicus' work, as well as Johannes Kepler's equations of planetary motion and Tycho Brahe's observations.

We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.

So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

(a) The ball’s maximum speed over the net is v(max) = √2gh.

(b) The maximum speed of the horizontally moving ball clearing the net is about 27 m/s.

(c) Speed of the ball is independent of its mass.

The time of motion of the ball is calculated as follows;

h = vt + ¹/₂gt²

1 = 0 + ¹/₂(9.8)t²

1 = 4.9t²

t² = 1/4.9

t² = 0.204

t = 0.452 s

The horizontal speed of the ball is calculated as follows;

X = vt

v = X/t

v = (12 m)/(0.452)

v = 26.6 m/s ≈ 27 m/s  (proved)

P.E = K.E

Answer:Radio works by transmitting and receiving electromagnetic waves. The radio signal is an electronic current moving back and forth very quickly. A transmitter radiates this field outward via an antenna; a receiver then picks up the field and translates it to the sounds heard through the radio.In AM (Amplitude Modulation) radio, the strength (amplitude) of the signal is changed (modulated) to make the sounds. In FM (Frequency Modulation) radio, it is the speed (frequency) of the signal that is changed. When you tune in your radio, the dial number indicates the kilo or megaHertz at which the signal is being broadcast.

Radio signal uses specific frequency, or how quickly the waves of the field move up and down. Hertz is a measurement of the number of wave cycles per second - AM is expressed in kiloHertz, while FM radio is expressed in megaHertz. The station power affects the range of the signal, or how far it can travel. The strongest AM power allowed in the United States is 50,000 watts.

Answer:

Upward: Negative

Downward: Positve

Explanation:

Let upward be positive

We want to find the work done on the object upwards.

The equation of work done due to gravity is

[tex]f _{g}d \cos( \alpha ) [/tex]

It is read as force of gravity times displacement times cos of the angle between the force and displacement.

Since gravity is happening down of the center of mass and the displacement is upwards, the angle is 180° so

[tex]f_{g}d \cos(180) [/tex]

Cosine of 180 is -1

so

[tex] - f_{g}d [/tex]

If we go downwards, the sign will be positive because cos(0)=1

The car A and car B are travelling at different speeds. The car that has a greater acceleration is car B.

Acceleration is defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

Car A is traveling with a constant velocity of 18 [m/s]. The initial and final velocity is same. So, the acceleration is given by

a = (18 -18)/ t

a = 0 m/s²

Car B speeds up from 0 [m/s] to 10 [m/s] in 4 seconds. The acceleration is

a = (10 -0)/ 4

a = 2.5 m/s²

Thus, the car B has greater acceleration.
