During lockdown, I ate LOADS OF JUNK FOOD. TRUST ME!!

I gained 14 kg of weight and became 68 kg

just due to junk food.I am 13 btw and at that time I was 5 feet 4 so definitely fat. all those pizzas and burgers and all.then I realised that I have gained weight. I have to REDUCE MY WEIGHT. I am quite determined on what I say. it took me 3 months or so and I finally got back to my original weight. How? just by going for a stroll everyday, eating healthy and constantly working out. eating less is not the solution,eating less calories is the solution.Also, by eating healthy food,I grew taller. I am 5 feet 6 now. So yes, definitely it helps put alot and keep eating healthy food and you will definitely be healthy.

Thank You.

Answer:

306 m/s

Explanation:

Law of conservation of momentum

m1v1 + m2v2 = (m1+m2)vf

m1 is the bullet's mass so it is 0.1 kg

v1 is what we're trying to solve

m2 is the target's mass so it is 5.0 kg

v2 is the targets velocity, and since it was stationary, its velocity is zero

vf is the velocity after the target is struck by the bullet, so it is 6.0 m/s

plugging in, we get

(0.1 kg)(v1) + (5.0 kg)(0 m/s) = (0.1 kg + 5.0 kg)(6.0 m/s)

(0.1)(v1) + 0 = 30.6

(0.1)(v1) = 30.6

v1 = 306 m/s

The initial velocity of the bullet can be determined from the total momentum of the system. The velocity of the bullet was 306 m/s.

Momentum of a body is the product of its mass and velocity. For a collision, the momentum before and after collision will be the same for the colliding system.

Let m1 and m2 be the masses and u be the initial velocity and v is the final velocity.

then,  m1 u1  + m2 u2 = m1 v1  + m2 v2.

Given m1 = 5 kg

m2 =  0.1 kg

The velocity of the combined mass v = 6 m/s.

The momentum of the target is zero since it was stationary.

(0.1 × u1) = (0.1 + 5)6 m/s

(0.1 × u1) = 30.6 m/s

then u1 = 30.6/0.1 = 306 m/s

Therefore, the velocity of the bullet before hitting was 306 m/s.

An unmanned spacecraft leaves for Venus. The statements, The weight of the spacecraft keeps changing and The mass of the spacecraft remains the same. This 2 statements A and D are true.

A spaceship is a machine or vehicle built to travel through space. Spacecraft are a form of artificial satellite utilised for a wide range of tasks, such as communications, Earth observation, meteorology, navigation, space colonisation, planetary exploration, and freight and person transfer. All spacecraft, with the exception of single-stage-to-orbit vehicles, need a launch vehicle (carrier rocket) to get into space.

A spacecraft that is performing a sub-orbital spaceflight launches into space and then lands without gaining enough momentum or energy to complete a full orbit of the Earth. Spacecraft enter confined orbits around the Earth or other celestial bodies for orbital spaceflights. Only humans are carried on human spacecraft either as crew or guests from launch or while in orbit (space stations).

Vibrations are sent through the air to your ears.

Explanation:

Sound is a form of energy that is transmitted in compression and rare factions. Sound is a mechanical wave. All mechanical waves require a material medium for propagation.

The material medium for the propagation of sound is air. When the sound is produced by the speakers, the molecules of air are set into vibration and this vibration carries the sound from the speaker to your ears.

Answer:

The wave diagramed in blue.

Explanation:

The reason for this is because frequency is explained as the number of times something has occurred in a certain period of time.

Here, we are talking about wavelength, so the frequency is the number of times the wave can oscillate in this time length.

Say we make dots on the middle of each downward slope. How long does it take to get to each dot compared to the other diagram? The answer is the one with the least amount of time. The wave diagramed in blue.

Answer:

RT = 35 Ohms

Explanation:

Let the three resistors be R1, R2 and R3 respectively.

Given the following data;

R1 = 14 Ohms

R2 = 12 Ohms

R3 = 9 Ohms

To find the total resistance, RT;

Since all the resistors are connected in series, the total resistance is equal to the sum of all three resistance of the resistors.

RT = R1 + R2 + R3

Substituting into the equation, we have

RT = 14 + 12 + 9

RT = 35 Ohms.

Therefore, the total resistance of the circuit is 35 Ohms.
