Answer:

[tex]\boxed {\boxed {\sf 4 \ meters}}[/tex]

Explanation:

Gravitational potential energy can be found using the following formula:

[tex]E_P=m*g*h[/tex]

where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the tiger is 12.5 kilograms. The gravitational acceleration on Earth is 9.8 m/s².

[tex]m= 12.5 \ kg \\g= 9.8 \ m/s^2\\E_p= 490 \ kg*m^2/s^2[/tex]

Substitute the values into the formula.

[tex]490 \ kg*m^2/s^2 = 12.5 \ kg * 9.8 \ m/s^2 *h[/tex]

Multiply 12.5 kg and 9.8 m/s²

[tex]490 \ kg*m^2/s^2 = 122.5 \ kg *m/s^2 *h[/tex]

Since we are trying to solve for h, we must isolate it. Since h is being multiplied by 122.5, we must divide both sides by that number because the inverse of division is the inverse of multiplication.

[tex]\frac{490 \ kg*m^2/s^2} { 122.5 \ kg *m/s^2}= \frac{ 122.5 \ kg *m/s^2 *h }{ 122.5 \ kg *m/s^2}[/tex]

Note that when dividing, the kg*m/s² will cancel each other out, but a m (meter) will be left.

[tex]\frac{490 \ m }{122.5} =h[/tex]

[tex]4 \ m =h[/tex]

The tiger was 4 meters above the ground.

Explanation:

Answer:

The initial velocity of the plane is 54.77 m/s

Explanation:

Given;

distance covered by the plane, d = 200 m

deceleration of the plane, a = - 7.5 m/s²

The initial velocity of the plane is given by the following kinematic equation;

v² = u² + 2ad

where;

v is the final velocity of the plane when the plane comes to a complete stop = 0

u is the initial velocity of the plane

0 = u² + 2(-7.5 x 200)

0 = u² - 3000

u² = 3000

u = √3000

u = 54.77 m/s

Therefore, the initial velocity of the plane is 54.77 m/s

Answer:

Option D. 23.5 m

Explanation:

From the question given above, the following data were obtained:

Frequency = 200 Hz

Speed of sound in brass = 4700 m/s

Wavelength of sound in brass =?

We can obtain the wavelength of the sound in the brass by using the following formula as illustrated below:

Wave speed = wavelength × frequency

4700 = wavelength × 200

Divide both side by 200

Wavelength = 4700 / 200

Wavelength = 23.5 m

Thus, the wavelength of the sound in the brass is 23.5 m

Answer:

The effects of the Moon's rotation includes;

1) The Moon rotation and revolution gives the appearance of a perfectly still Moon to observers of the Moon from the Earth

2) The Moon has two sides, the near side that continuously faces the Earth and the "back" or far side, which is also known as the dark side of the Moon

The effect of the Moon's revolution

1) The tides in the ocean and water bodies, due to the gravitational forces from the Moon

2) The changes in the observed shape of the Moon due to the amount of Sunlight that is able to be reflected from the Moon as a result of the relative position of the Moon, the Earth and the Sun, at a given point in time

3) Lunar and Solar eclipse, when the Earth and the Moon blocks the light coming from the Sun respectively, due to their combined revolution

Explanation:

The duration of the Moon's orbit round the Earth = 27.322 days

The time it takes the Moon to rotate round its axis = 27 days

The Moon is the closest cosmic body to the Earth.

Answer:

percentage by volume of the solute = 45%

Explanation:

The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.

In this example,

volume of solution = 300mL

volume of solute = 135mL

% volume of solute = (volume of solute ÷ volume of solution) × 100

= (135 ÷ 300) × 100

= 0.45 × 100 = 45%

∴ percentage by volume of the solute = 45%

Answer:

empty space

Explanation:

Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.

Hence, it can be concluded that Most of our Solar system is composed of "Empty Spaces."

Answer:

you are right Gravity attracts larger objects only if they are close to one another. If the masses of the objects increase, then the force between them also increases. If distance between the objects increases, then the amount of force also increases. Y Z​ this is the answer .

D

Explanation:

She says that the object of the experiment is to see how far the string stretches given a mass attached to the string.

The only thing that is at issue is either the mass or the amount the string stretches.

Nothing else matters.

The dependent variable therefore is the amount the string stretches. So the last choice is the answer.

Answer:

Explanation:

Synthetic fabrics, such as nylon and polyester, are produced entirely from chemicals. Natural fabrics, such as cotton, silk, and wool are made of fibres from plants and animals. Synthetic fabrics are useful because they have very different or enhanced (improved) properties in comparison to natural materials.

Answer:

Explanation:

The formula for weight goes- Weight=Mass*Gravity

We need to re arrange the formula in order to find the mass

so, mass=w/g

~If the person is on Earth then we can substitue the official the value of gravity as 9.8m/s^2 (this value is fixed)

~ The weight given in this question is 7,056 kN , but we need the weight to be in Newtons for the formula to acc work. So converting  7,056 kN to newtons would give 7056000N. (Newton = Kilonewton * 1000)

Now all we need to do is compute these values-

M=  7056000/9.8

M=720000kg

Well, thats the ans

Answer:

1.1 lbs

Explanation:

To convert kg to lbs you multiply kilograms by 2.2. So 0.5kg × 2.2 equals to 1.1 lbs

Answer:

the sun light will heat up the balloon causing it to burst

Answer:

well, mercury is the closest planet to the sun, making it MUCH hotter than earth. that being said, just because mercury is closest to the sun, it doesnt mean its the hottest planet.

Since Mercury is the planet that is nearest to the sun, it is much hotter than the earth. However, because Mercury is nearest to the sun doesn't automatically make it the hottest planet.

A huge, spherical celestial object, it is neither a star it nor remnant is called a planet. The nebular concept, which holds how an interplanetary cloud collapse out of a nebula to produce a young white dwarf orbited by a planetary system, is the best theory currently available for explaining planet formation.

The slow buildup of matter propelled by gravity—a practice called as accumulation, to the formation of planets in this disk. The rocky planets Mercury, Venus, Earth, and Mars, as well as the giant planets Jupiter, Saturn, Uranus, and Neptune, make up the Solar System's minimum number of eight planets. Each of these planets revolves around an axis that really is inclined with regard to its orbit pole.
