When a beam of light is incident on a surface, it delivers energy to the surface. The intensity of the beam is defined as the energy delivered per unit area per unit time.
What is the unit of intensity, expressed in SI base units?
Answer:
Kg
Explanation:
Given that the definition of intensity is:
The intensity of the beam is defined as the energy delivered per unit area per unit time. That is,
I =( E × t)/A
Which can expressed as
I = J/m^2/s
The S.I Units of
Energy is Joule = kgm^2s^-1
Area A = m^2
Time t = s
Intensity I = kgm^2s^-1 × m^-2 × s
Intensity I = kg
The cubic metres and seconds are cancelled out
Therefore, the S.I units of intensity is kg

Astronauts who traveled to the moon were able to float slightly as they walked along its surface. Why were the astronauts able to do this? The weight of the astronaut on Earth is less than his weight on the moon. The mass of the astronaut on Earth is less than his mass on the moon. The weight of the astronaut on Earth is greater than his weight on the moon. The mass of the astronaut on Earth is greater than his mass on the moon.
Answer: The weight of the astronaut on earth is greater than his weight on the moon.
Explanation:
The reason I got this answer is because the astronaut will have the same mass on the moon as he does on earth. Also the weight of a person or object is determined by gravity. So since the moons gravity isn’t as strong as earths gravity the astronauts are lighter in terms of weight, and this is how they slightly float.
The weight of the astronaut on Earth is greater than his weight on the Moon. The third option is correct.
What is gravity?The force of attraction felt by a person at the center of a planet or Earth is called as the gravity.
The Earth has the acceleration due to gravity, g = 9.81 m/s², Moon has the acceleration due to gravity 6 times less than that of Earth.
Astronauts who traveled to the Moon were able to float slightly as they walked along its surface. The astronauts were able to do this because they have the same mass on the Moon as he does on Earth.
The weight of a person or object is determined by gravity. Since, the Moon's gravity isn’t as strong as Earth's gravity. So, the astronauts slightly float on Moon.
The weight of the astronaut on Earth is greater than his weight on the moon.
Thus, the third option is correct.

Which is always true in a closed system?
Acceleration is not constant.
Mass is not conserved.
Momentum is conserved.
Velocity is constant.
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
C: Momentum is consevered

water in a cup and a kettle can have the same temperature even though the quantities are different . give reasons
Answer:
The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature, [tex]T_{(equilibrium)}[/tex] reached is the same for both the cup and the kettle as given by the relation;
[tex]\infty M_{(environ)} \times c_{(environ)} \times (T_2 - T_1) = m_{1} \times c_{(water)} \times (T_3 - T_2) + m_{2} \times c_{(water)} \times (T_4 - T_2)[/tex]
Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment

A load of 800 N is lifted using a block and tackle having 5 pulleys. If the applied effort is 200 N, calculate
i. Mechanical advantage
ii. Velocity ratio
iii. Efficiency
iv. Output work if load is lifted 5m high.
v. Input work
Explanation:
Load=800N
Effort=200N
1. Mechanical Advantage = LOAD/EFFORT
= 800N/200N
= 4
2 Velocity Ratio = no. Of pulleys =5
3. Efficiency = Mechanical advantage / velocity ratio × 100%
= (4/5)×100%
=80%
4. output work= load×load distance
= 800N × 5m
= 4 × 1000J
5. Efficiency = (output work/input work) ×100%
Or, 80% = (4000J/input work) ×100%
Or, 80%/100% = 4000J/inputwork
Or, 4/5 = 4000J/inputwork
Or, input work =4000J × 5/4
Input work = 5×1000J
