An engine raises 100kg of water through a height of 60m in 20s. what is the power of the engine

Answers

Answer:

the answer is 3000

Explanation:

power=mass×gravity×height or (divided by /Time)

so 100kg×10×60m/20s

=60,000/20

=3000joule

Which of the following has the greatest frequency? a loud middle c note a soft middle c note a note lower than middle c a note higher than middle c?

Answers

a note higher than middle c has the greatest frequency. Hence option D is correct.

What is Wave ?

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform. There are two types of the wave longitudinal wave and transverse wave.

Hence option D is correct.

A solar eclipse might be observed from Earth when the moon is in which position

Answers

A solar eclipse might be observed from Earth when the moon is in the newmoon phase.

What would be observed from the Moon while Earth is experiencing a solar eclipse?

During the lead-up to a solar eclipse from the Moon, a viewer on the Moon would see the Sun approach the dark disk of Earth, with the planet's nightside facing the Moon. Earth's atmosphere would be lit from behind, creating a reddish ring around the planet that would glow brighter as the eclipse proceeded.

When can you see the solar eclipse?

We will finally see a total solareclipse on April 8, 2024, in North America and Central America. The total phase will be visible from Mexico, the central United States, and eastern Canada. Another eclipse in 2024, an annular one, will take place on Oct. 2.

A ball is thrown horizontally from the top of a building 0.10 km high. The ball strikes the ground at a point 65 m horizontally away from and below the point of release. What is the speed of the ball just before it strikes the ground?

Answers

The speed of the ball just before it strikes the ground is equal to 46.55 m/s.

Given the following data:

Horizontal distance = 65 meters

Height of building = 0.10 km = 100 meters

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 $m/s^2$ .

To determine the speed of the ball just before it strikes the ground:

First of all, we would determine the time it took the ball to strike the ground by using the formula for maximum height.

$H = (1)/(2) gt^2\n\n100 = (1)/(2) * 9.8 * t^2\n\n200 = 9.8t^2\n\nt^2 = (200)/(9.8) \n\nt^2=20.41\n\nt=√(20.41)$

Time, t = 4.52 seconds

Next, we would find the horizontal velocity:

$Horizontal\;velocity = (horizontal\;distance)/(time) \n\nHorizontal\;velocity = (65)/(4.52)$

Horizontal velocity, V1 = 14.38 m/s

Also, we would find the velocity of the ball in the horizontal direction:

$V_2^2 = U^2 + 2aS\n\nV_2^2 = 0^2 + 2(9.8)(100)\n\nV_2^2 = 1960\n\nV_2 = √(1960) \n\nV_2 = 44.27 \;m/s$

Now, we would calculate the speed of the ball just before it strikes the ground by finding the resultant speed:

$V = √(V_1^2 + V_2^2) \n\nV = √(14.38^2 + 44.27^2)\n\nV = √(206.7844‬ + 1959.8329‬)\n\nV =√(2166.6173)$

Speed, V = 46.55 m/s

Answer:

v = 46.55 m/s

Explanation:

It is given that,

A ball is thrown horizontally from the top of a building 0.10 km high, d = 0.1 km = 100 m

The ball strikes the ground at a point 65 m horizontally away from and below the point of release, h = 65 m

At maximum height, velocity of the ball is 0. So, using the equation of motion as :

$d=ut+(1)/(2)at^2$

Here, a = g

$100=0+(1)/(2)* 9.8t^2$

$t=4.51\ s$

Let $v_x$ is the horizontal velocity of the ball. It is calculated as :

$v_x=(65\ m)/(4.51\ s)=14.41\ m/s$

Let $v_y$ is the final speed of the ball in y direction. It can be calculated as :

$v_y^2+u_y^2=2as$

$u_y=0$

$v_y^2=2gd$

$v_y^2=2* 9.8* 100$

$v_y=44.27\ m/s$

Let v is the speed of the ball just before it strikes the ground. It is given by :

$v=√(v_x^2+v_y^2)$

$v=√(14.41^2+44.27^2)$

v = 46.55 m/s

So, the speed of the ball just before it strikes the ground is 46.55 m/s. Hence, this is the required solution.
