A laser beam is directed at the Moon, 380,000 km from the Earth. The beam diverges at an angle of \thetaθ of 0.8 x 10-5 rad. What diameter spot, in m, will it make on the Moon?
Answer:
3040 m
Explanation:
The formula to apply here is ;
d=∅*r where
d is the diameter of the spot , ?
∅ is angle of divergence in radians, = 0.8 * 10⁻⁵rad
r is distance of Moon from Earth, =380,000 km
Applying the formula as;
d=∅*r

The figure below shows a slide in a children's playground
Metal ladder
Metal support
(a)
A child of mass 18 kilograms goes down the slide
The vertical distance from the top to the bottom of the slide is 2.5 metres.
Calculate the decrease in gravitational potential energy of the child sliding from the
top to the bottom of the slide.
Gravitational field strength = 10 N/kg
Decrease in gravitational potential energy
(2)
Answer:
P = 450 J
Explanation:
Given that,
Mass of a child, m = 18 kg
The vertical distance from the top to the bottom of the slide is 2.5 metres.
The Gravitational field strength = 10 N/kg
We need to find the decrease in gravitational potential energy of the child sliding from the top to the bottom of the slide.
The formula for the gravitational potential energy is given by :
P = mgh
Substituting all the values,
P = 18 kg × 10 m/s² × 2.5 m
P = 450 J
Hence, the decrease in gravitational potential energy is 450 J.

Which law is stated below?
The acceleration of an object is proportional to the force applied to it and
inversely proportional to its mass.
A. The law of inertia
B. Newton's first law
C. Newton's third law
D. Newton's second law
Answer:
D. Newton's second law
Explanation:
Newton's second law of motion states that force of an object is a product of its mass and its acceleration.
Mathematically, F= ma where m is mass and a is acceleration
So from the statement above : The acceleration of an object is proportional to the force applied to it and inversely proportional to its mass , it can be seen from the formula variation as;
F= ma -----making a the subject of the formula
a= F/ m
a= 1/m * F --------- a is inversely related to m as you can see from 1/m but directly related to F hence;
Increase in mass with the same force applied causes the body to accelerate slower where as when force increases, the body accelerates faster.
How much water is displaced by a solid object with a volume of 9 cm3 that is completely submerged in the water?
Given :
An object with a volume of 9 cm³ is completely submerged in the water.
To Find :
How much water is displaced by the object.
Solution :
According to Archimedes' principle, the amount of volume displaced of fluid when an object is fully and partially submerged into that is equal to the volume of the object below the surface of liquid.
Now, it is given that object is fully submerged into water.
Therefore, volume of water displaced by the object is 9 cm³.
A girl during a hike has a bottle of mineral water in her haversack. The bottle has 2 litres of water in it (2ltr. weigh 2kg). The water gets heated by the sun by 5 °C. How much heat has the water absorbed from the sun?
Answer:
Q = 41800[J]
Explanation:
These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.
[tex]Q=m*C_{p}*DT[/tex]
where:
Q = Heat absorbed [J]
m = mass = 2 [kg]
DT = temperature change = 5 [°C]
Cp = specific heat of the water = 4180 [J/kg*°C]
[tex]Q=2*4180*5\\Q=41800[J][/tex]

What are the characteristics of a blackbody radiator? Give an example.
Answer:
A blackbody, or Planckian radiator, is a cavity within a heated material from which heat cannot escape. No matter what the material, the walls of the cavity exhibit a characteristic spectral emission, which is a function of its temperature.
Example:
Emission from a blackbody is temperature dependent and at high temperature, a blackbody will emit a spectrum of photon energies that span the visible range, and therefore it will appear white. The Sun is an example of a high-temperature blackbody.
Given the impulse acting on an object and the impact time which equation can be used to calculate the force applied to an object
Answer is D
Ndmdjdndbdjdkskd
The impulse acting on an object and the impact time, the equation F= I / Δt can be used to calculate the force applied to an object, therefore the correct answer is D.
What is impulse?The product of the average applied force and the time for which it is exerted is known as an impulse.
the mathematical relation for impulse is
Impulse = F * Δt
where F represents the force applied and Δt represents the time for which the force is applied
Thus, the correct equation that can be used to calculate the force applied to an object is F = I /Δt and the correct option is D.

Intact fossils are usually found in sedimentary rock, not metamorphic rock. Based on the information in the diagram, what is the reason for this phenomenon?
Explanation:
The reason for this phenomenon is the due to the condition by which each type of rocks form.
A sedimentary rock is formed by the compaction and lithification of sediments within a basin.
A metamorphic rock forms under high temperature and pressure conditions which alters the minerology of a rock.
Based on these conditions, the metamorphic rock cannot host any fossil. Any relics of fossils would be destroyed at such elevated pressure and temperature conditions. This is not so in a sedimentary rock because the conditions are similar to that which can preserve organic matter.Answer:
The heat and pressure of metamorphism would deform the fossil, and the process of melting would destroy the fossil completely.

According to the law of conservation of energy, mechanical energy can be changed to heat energy.
Answer:
The answer to this question is given below in this explanation section.
Explanation:
" law of conservation of energy"
The law of conservation of energy states that energy can neither be created nor destroyed only converted from one form of energy into another.This mean that a system always has a same account of a energy,unless it is added from the outside.This is particularly confusing in the case of non conversation forces,where energy is converted from ,mechanical energy into thermal energy.but the overall energy does remain the same.The only way to use energy is to transform energy from one form to another.
The amount of energy in any system than it is determined by the following equation.
Ut=Ui +W+Q
Ut is the total internal energy of a system.Ui is the initial internal energy of a system.W is the work done by or on the system.Q is the heat added to or removed by the system.It is also possible to determined the change in internal energy of the system using the equation.
ΔU=W+Q
The mechanical energy of a system increases provided their is no loss of energy due to friction.The energy would transform to kinetic energy when the speed is increasing.Te mechanical energy of a system remain constant provided their is no loss of energy due to friction.
The law of conversation of energy which say that in a closed system total energy is conserved that is it constant.
