Answer:
Explanation:
According to the conservation of momentum, if she throws the camera in the opposite direction of space shuttle, she drifts towards the shuttle.
The correct answer is (d), electrons are in probable cloud location.
An atom is made up of three fundamental particles, electron, proton and neutron. Proton and neutron are located in the nucleus, while the electrons orbit the nucleus in relative large orbit, however the exact position of the electron in the shall is highly unpredictable, therefore they are assumed to be in probable cloud location where the probability of finding an electron is very high.
Answer:
102000 kg
Explanation:
Given:
A total Δν = 15 km/s
first stage mass = 1000 tonnes
specific impulse of liquid rocket = 300 s
Mass flow rate of liquid fuel = 1500 kg/s
specific impulse of solid fuel = 250 s
Mass flow of solid fuel = 200 kg/s
First stage burn time = 1 minute = 1 × 60 seconds = 60 seconds
Now,
Mass flow of liquid fuel in 1 minute = Mass flow rate × Burn time
or
Mass flow of liquid fuel in 1 minute = 1500 × 60 = 90000 kg
Also,
Mass flow of solid fuel in 1 minute = Mass flow rate × Burn time
or
Mass flow of solid fuel in 1 minute = 200 × 60 = 12000 kg
Therefore,
The total jettisoned mass flow of the fuel in first stage
= 90000 kg + 12000 kg
= 102000 kg
Answer: Option (A) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.
And, when gas particles move slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.
Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
