Answer:

W = 1.96 J

Explanation:

Given that,

The mass of an Apple, m = 100 g = 0.1 kg

It fell from 2 metres high tree.

We need to find the work done by it. The work done is given by :

[tex]W=mgh\\\\W=0.1\times 9.8\times 2\\W=1.96\ J[/tex]

So, the required work done is 1.96 J.

C.( Alpha particles!

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.

Answer:

D

Explanation:

F=ma

F of 5 kg rock = 49N

F of 10 kg rock = 98 N

Divide by respective masses to get acceleration, and of course you will get 9.8 m/s^2 for both.

Now, use potential energy equals kinetic energy. mgh=(1/2)mv^2 mass cancels out of the equation, since it's on both sides, so we can stop right there. We have algebraically determined that mass does not affect acceleration or velocity!

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

PLS ANSWER MY QUESTION TOO

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:

Higher frequency.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the speed of a sound is given by the formula:

[tex] Speed = wavelength * frequency [/tex]

Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.

A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.

Hence, shrill sound is of higher frequency.

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.

Why does the moon appear to change its shape as seen from Earth

Answer:

14metre squared

Explanation:

acceleration=force/mass

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.
