Answer:

Energy by definition is the property of matter that involves interactions with molecules, in order to perform an action.

Explanation:

They're many different types of energy, a few of them are...

. Thermal energy
. Solar energy
. Chemical energy
. Kinetic energy
. Potential energy
. Mechanical energy to name a few...

All of these specific energies involve the interaction of molecules which are used for different things and can be converted from one type of energy to another.

Answer: 4500 m

Explanation:

[tex]15 min. * \frac{240 m}{min.} = 3600 m[/tex]

[tex]10 min. * \frac{90m }{min.} = 900 m[/tex]

[tex]3600m +900m = 4500m[/tex]

Answer:

5 m/s2

Explanation:

Using the equation velocity = initial velocity + (acceleration x time)

30 m/s = 0 + acceleration x 6 s

30 m/s = 6 s x acceleration

30 m/s / 6s = acceleration

acceleration = 5 m/s2

We will increase the amplitude of the wave by a factor of 4 If we want to double this rate

Transverse wave, travels in a way in which points on a wave oscillate along paths at right angles of 90 degrees to the direction of the wave.

We see that energy transported along a wave path is directly proportional to the square of the amplitude.

E =kA^2

Therefore, we will increase the amplitude of the wave by a factor of 4 If we want to double this rate.

Friction is the force that opposes motion.

The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.

1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.

2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.

Explanation:

The sulphur atom has 6 electrons in the outermost shell, and its valency could be 6. But it is easier for sulphur to gain two electrons instead of losing six electrons. Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur.

i don't know how to explain it but I think it's just the way you do it by yourself

A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.

Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.

A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.

v² = u² + 2 × a × s

v² = (0 m/s)² + 2 × (9 m/s²) × 240 m

v = 66 m/s

where,

Answer: The resultant displacement vector is 5.6km

The resultant displacement vector of the hiker is equal to 5.6 km.

The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.

The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.

Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.

The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (5.0)² + (2.5)²

AC² = 25 + 6.25

AC = 5.59 km ≈ 5.6 km

Therefore, the displacement of the hiker is 5.6 Km.

Explanation:

The radius of each jawbreaker is approximately 0.68 cm.

where

r = radius

Therefore,

23 g  = 32.3 cm³

0.94 g  = ?

cross multiply

volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³

Therefore,

volume of each jawbreaker = 4 /3 πr³

1.32 = 4 / 3 × 3.14 × r³

r³ = 1.32 /4.18666666667

r³ = 0.31533683707

r = ∛0.31533683707

r = 0.680651651 = 0.68

Therefore, the radius of each jawbreaker is approximately 0.68 cm.
