Answer:

All matter is made up of very small particles called atoms.

if a charged object touches a neutral object it will be a short circuit.

Answer:

will force atom(electrons) within the escort (conductor) to go (move).

Answer:

Atoms are made up of even smaller particles called protons, electrons & neutrons (sub-atomic particles)

Atoms are made up of smaller particles called subatomic particles.

An atom is defined as the smallest indivisible particle of an element. It is made of subatomic particles which are:

Now the Neutron and Proton make up the nucleus which is at the core(middle) of the atom whole the electron rotates around the orbits that  surrounds the nucleus.

The Neutron has no charge.

The Proton is positively charged.

The electron is negatively charged.

The distance moved by the object in the direction of the force is equal to 16 m. Therefore, option (B) is correct.

Work can be demonstrated as the energy employed when a force is exerted to move an object through a specific distance. The work done depends upon both the exerted force on the object and the displacement.

The action of the force when the object is moving in a straight line in the direction of the exerted force over a distance 'd'.

W= F ×d

Where 'd' is the displacement, 'F' is the applied force and W is the work done.

Given, the work done by the applied force, W = 400 J

The force applied on the object, F = 25 N

The distance moved by the object, d = W/F

d = 400/25

d = 16 m

Therefore, the object moves a distance of 16 m in the direction of the force.

Answer:

Explanation:

Carbon dioxide in photosynthesis Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata . (singular: stoma. plural: stomata) The lower part of the leaf has loose-fitting cells to allow carbon dioxide to reach the other cells in the leaf.

Answer:

Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.

Answer:

GPEb=67.86% of initial GPE at point a

Explanation:

It depends on how massive the ball is, but I can still give an answer comparing original GPE at point A to new GPE at B

GPEa=m*9.8*140

GPEa=1372(m)

GPEb=m*9.8*95

GPEb=931(m)

GPEb=0.6786*GPEa

Answer:

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

Answer:

1. Scalar_100° Celsius

2. Vector_50 m/s²

3. Scalar_300 s

4. Vector_250 m/s, northwest

5. Vector_1m, to the right

6. Vector_10 cm, upwards

7. Scalar_525 600 mins.

8. Vector_90 km/h,east

8. Scalar_5 000 kg

10. Scalar_1.5 L

Explanation:

A scalar quantity can be defined as a quantity that has magnitude but no direction. Some examples of scalar quantities are speed, mass, temperature, volume, length, etc.

On the other hand, a vector quantity has both magnitude and direction. Some examples of vector quantities are acceleration, velocity, displacement, etc.

1. Scalar_100° Celsius (Temperature).

2. Vector_50 m/s² (Acceleration).

3. Scalar_300 s (Time).

Answer:

a. t = 1.43 s

b. d = 7.88 m

Explanation:

a. The time of flight can be found using the following equation:

[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]

Where:

[tex]y_{f}[/tex]: is the final height = -10 m

[tex]y_{0}[/tex]: is the initial height = 0

[tex]v_{0_{y}}[/tex]: is the initial speed in the vertical direction = 0

g: is the acceleration due to gravity = 9.81 m/s²

By solving the above equation for "t" we have:

[tex] t = \sqrt{\frac{2y_{f}}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]

Hence, the ball will hit the ground in 1.43 s.

b. The distance in the horizontal direction can be found as follows:

[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]

Where:

x₀: is the initial position in the horizontal direction = 0

a: is the acceleration in the horizontal direction = 0 (it is moving at constant speed)

[tex] x_{f} = 5.51 m/s*1.43 s = 7.88 m [/tex]

Therefore, the ball will travel 7.88 m before it hits the ground.

Answer: 25500 joules

Explanation: E = P x t

Answer:

Velocity increases

Explanation:

Gravity is constant, except when discussing "apparent weight"

Mass is constant here

Air resistance would actually increase

Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.

Explanation:

Net force is the sum total of forces acting on an object.

The Fn which is the net force is

450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)

= 450-250+(-600)+ 600+0+250-450

= 0N

The net force is 0
