At the peak of its flight ALL the energy given to the rocket is potential energy (its velocity is zero) and that is calculated as mgh So Energy given to rocket = mgh Energy expended by engine = F x D (D= height where engine stops) Energy 'lost' to drag is the difference between the two values. please if this helped mark it as the brainiest answer.
The total distance you would have covered is equivalent to going around the earth 22 times.
<h3>
Total distance traveled</h3>
The total distance traveled at a given speed and time of motion is calculated as follows;
Distance = speed x time

<h3>Distance round the Earth</h3>
The distance round the earth or circumference of the earth of the earth has been given as 25,000 miles
<h3>Number of times round the earth</h3>

Thus, the total distance you would have covered is equivalent to going around the earth 22 times.

Answer:
The magnitude of the acceleration of the electron at this point is
.
Explanation:
Given that,
Velocity 
Angle = 61.5°
Magnetic field = 0.01 T
We need to calculate the magnetic force
Using formula of magnetic force

Where, B = magnetic field
v = velocity
e = charge of electron
Put the value into the formula


We need to calculate the acceleration
Using newton's second law


Put the value into the formula


Hence, The magnitude of the acceleration of the electron at this point is
.
Answer: i'm not fully sure but i think it's A.
Explanation: why do i think the answer is a? well the parallel circuit definition is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. which means that if you unscrew/remove one bulb it would still work, but in a series circuit it will not work, because if you remove one it turns all the bulbs off.
Answer:
v = - 14.08 m / s
Explanation:
The definition of center of mass is
= 1 /M ∑sun 
where M is the total mass of the system and
and
are the position and mass of each component.
The velocity of the center of mass can be found by deriving this expression with respect to time
= 1 / M ∑ m_{i}
vi
let's find the total mass
M = m₁ + m₂ + m₃ + m₄
M = 1.45 + 2.81 +3.89 + 5.03
m = 13.18 kg
let us substitute in the velocity of the center of mass
= 0
0 = 13.18 (m₁ v₁ + m₂ v₂ + m₃v₃ + m₄v₄)
v₄ = - (m₁ v₁ + m₂ v₂ + m₃v₃) / m₄
let's substitute the given values
v₄ = -[1.45 (6.09 +0.299 t) +2.81 (7.83 + 0.357t) +3.89 (8.09 + 0.405 t)] / 5.03
They ask us for the calculations for a time t = 2.83 s
v₄ = - [8.8305 + 1.227 + 22.00 + 2.839 + 31.47 +4.4585] / 5.03
v = - 14.08 m / s
