Answer:

This question is incomplete

Explanation:

This question is incomplete but the missing figure is in the attachment below.

When an object is travelling around a circular path, there is a force that tends to draw that object towards the center of the circular path and keep the object moving in the curved path, that force is called the centripetal force. From this description, it can be deduced that the direction of the centripetal force that acts on the car (in the attachment below) is D.

The name of the force that provides this centripetal force is frictional force. This is the force that prevents the car from slipping off the road; keeping it moving in the curved path.

Answer:

As the earth travels around the sun during the year it maintains this tilt. Because of this tilt, in the summer we (north of the equator) are slanted more directly towards the sun so it's hotter. In the winter, we're slanted away so the sun's rays are less direct, making it colder.

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:

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

yes yes true

Answer: The coefficient of friction is 0.35

Explanation:

We can write the friction force as:

F = N*μ

Where N is the normal force between the refrigerator and the ground, as the full weight of the refrigerator is acting on the ground, the normal force will be exactly equal to the weight of the refrigerator, then:

N = 650N

And μ is the coefficient of friction.

And for this case, the force is 230N, then we have:

F = N*μ

230N = 650N*μ

(230N/650N) = μ = 0.35

Notice that the distance did not matter for this calculation.

i) 5 [tex]m[/tex]/[tex]s^{2}[/tex]  ii) 54 [tex]N[/tex]  iii) 54 [tex]N[/tex]

Explanation:

i) [tex]a = \frac{v^{2}}{r}[/tex] ⇒ [tex]a[/tex] = 5² ÷ 5 = 5 [tex]m/s^{2}[/tex]

ii) [tex]m = \frac{W}{g}[/tex] ⇒ [tex]m[/tex] = 108 ÷ 10 = 10.8 [tex]kg[/tex] , [tex]F = ma[/tex] ⇒ [tex]F =[/tex] 10.8 × 5 = 54 [tex]N[/tex]

iii) F1 = F2 = 54 [tex]N[/tex]

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:

Direct current

Explanation:

Because it cannot reverse, and it's optimum for usage by electric home appliances.

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.

i dont know dude but ask someone who is in your grade lol

Explanation:

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.

Answer:

33,333.33 N

Explanation:

Given that :

Initial kinetic energy = 500,000 J

Final kinetic energy = 100,000 J

Using the relation :

Force * time = change in momentum (Newton's law)

Force (F) * 0.12 = (500,000 - 100,000)

0.12F = 400,000 J

Force = (400,000 J) / 0.12s

Force = 33333.333

Force = 33,333.33 N
