A gas when a fixed mass is compressed into a smaller volume then b) density increases.
Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Symbol: D or ρ Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
Mass is the measure of object's inertia, more the mass more the inertia. It is a property of material , so it does not change with place. SI unit is 'kg'. It is a scalar quantity.
Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. It means the amount of three-dimensional space a closed figure can occupy is measured by its volume.
Density = mass / volume
if mass is fixed, then mass = constant
Density will be inversely related to volume
hence , on compression , volume get decreased but mass is constant hence , density will increase

Safety belts and occupant protection systems are installed to reduce the harmful effects of the force of _____ during a collision.
To lessen the negative impacts of the force generated during a collision, safety belts and occupant protective relays are installed.
Importance of safety belts:
The purpose of a seat belt usually referred to as a safety belt or a safety belt, is to protect the driver or an occupant of a vehicle from a potentially dangerous movement that may occur during an accident or an abrupt stop. By minimizing the power of secondary hits with interior striking hazards, maintaining proper occupant positioning for the airbag, and preventing people from being expelled from the vehicle after an accident or if the automobile rolls over, seat belts help minimize the chance of a fatal accident in traffic collisions. When the car is moving, the passenger and the driver move together with it at the same pace.The occupants continue moving at the same pace the vehicle was traveling at when it stopped if it unexpectedly stops or crashes. To stop the driver and other passengers from exiting the vehicle or contacting the interiors of the vehicle, seatbelts apply an equal and opposite force to them. Due to their crucial function in occupant safety, seatbelts are regarded as the main restraint devices.Learn more about safety belts here:

A sample of an ideal gas is heated, and its kelvin temperature doubles. What happens to the average speed of the molecules in the sample?
A sample of an ideal gas is heated, and its kelvin temperature doubles. The average speed of the molecules in the sample will increases by a factor of [tex]\sqrt{2}[/tex]
The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.
Root mean square speed is a statistical measurement of speed.
The root mean square speed can be calculated as : V1 : [tex]\sqrt{3 R T / Mo}[/tex]
if temperature becomes double
let T1 is initial temperature
So , T2 = 2 * T1
now ,
Root mean square speed will be (V2) = [tex]\sqrt{(3 R (2T)) / Mo}[/tex]

Heat is transferred from the sun-warmed surface of the earth to the cooler overlying troposphere via conduction.
Heat transfer from earth to atmosphere:Conduction, convection, latent heating, and water phase transitions all help to carry heat from the Earth's surface, which has been warmed by the Sun, to the cooler troposphere above.
Latent heat flux is the worldwide transfer of latent heat energy via water and air currents. Here, we demonstrate how air circulation transports latent heat energy horizontally to cooler regions, where it condenses into rain or is deposited as snow, releasing the heat energy that was previously trapped there.

The cost of energy for pressing is 54 Kobo.
Units of electricity are measured in kilowatt-hours (kWh).
900-watt electric iron
Appliance usage = 4 hours a week for 5 weeks
The unit cost of electricity = 3 Kobo per kWh
Convert the wattage of the electric iron from watts to kilowatts.
1000 watts (W) = 1 kilowatt (kW)
⇒ 900 watts = 1 ÷ 1000 = 0.9 kilowatts
This means that the power consumption of the electric iron is 0.9 kW per hour of use.
Total hours spent pressing clothes:
= 4 hours per week for 5 weeks
= 4 × 5
= 20 hours
Total power consumption:
= number of kW × number of hours
= 0.9 × 20

At what temperature must a hot reservoir operate in order to achieve a 30arnot efficiency when the cold reservoir operates at 200 °c?
At temperature 402.71° C must a hot reservoir operate in order to achieve a 30% Carnot efficiency when the cold reservoir operates at 200 °C.
The Carnot engine is a theoretical thermodynamic cycle proposed by Leonard Carnot. It estimates the maximum possible efficiency that a heat engine during the conversion process of heat into work and, conversely, working between two reservoirs can possess.
The Carnot efficiency depends only on the temperature of the hot source and the cold sink. Carnot efficiency describes the maximum thermal efficiency that a heat engine can achieve as permitted by the Second Law of Thermodynamics.
Given
Efficiency = 30 %
T2 = absolute temperature of the heat source = T2
T1 = absolute temperature of the heat sink = 200 °C
efficiency = T2 - T1 / T2
30 /100= T2 - 200 / T2

Electrolysis can be used to purify silver. What mass of silver would plate onto the pure electrode if a current of 6. 8 a flowed through the cell for 72 minutes?
32.88grams of (Ag) silver would plate onto the pure electrode if a current of 6. 8A flowed through the cell for 72 minutes.
Silver can be electroplated at the cathode of an electrolysis cell by the half-reaction:
Ag+(aq)+e→Ag(s).
By Using the equation
Q= I×t, where Q = charge
I = current = 6.8 A
t= time in seconds= 72×60=4320s
So,
Q=6.8×4320
Q = 29,376C
We see that 1 mole of electrons produces 1 mole of Ag from the half reaction.
1mole of electrons= 96,500C
xmoles of electrons= 29,376C
Cross multiplying;
29,376= 96,500 × x
Now , dividing both sides of the by 96,500
29,376/96,500=x
0.3044 moles of electrons will produce
0.3044×108 = 32.88grams of Ag

μk = 0.106 is the coefficient of kinetic friction between the box and the floor
When the box is moving across the flat surface with a constant velocity, the force applied to it must be equal to the kinetic frictional force applied to the object:
F = μk*W = μk*mg
Where,
F = Force applied on box = 52 N
m = mass of box = 50 kg
g = 9.8 m/s²
μk = coefficient of kinetic friction between box and floor
hence,
52 N = μk(50 kg)(9.8 m/s²)
μk = (52 N)/(490 N)
μk = 0.106

On connecting a 9V battery to a Capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2. 0 mm. The charge on the positive plate is 544.7 ×10⁻¹² C.
Capacitance of the capacitor is determined by the area of the plate of Capacitor and distance between the plates of capacitor.
Let the area of the Capacitor be A , radius of circular plates be r and distance between the plates of capacitor be d.
Given, Voltage, V = 9V
Radius, r = 0.066m
Distance, d = 2mm = 0.002m
Area of the Capacitor, A = πr²
A = π(0.066)²
A = 0.013m²
Capacitance, C = ε₀A / d
C = 8.85×10⁻¹²×0.013/0.002
C = 60.5 ×10⁻¹² F
C = 60.5 pF
We know that Q = CV where Q is the charge on capacitor.
Q = 60.5 ×10⁻¹² × 9

What did you observe when placing the small coil in the middle of the larger coil?
With more turns of wire within the coil, the greater the strength of the static magnetic field around it.
Electromagnetic induction uses the relationship between electricity and magnetism whereby an electric current flowing through a single wire will produce a magnetic field around it. If the wire is wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving a distinct North and South pole.
Likewise, if we kept the bar magnet stationary and moved the coil back and forth within the magnetic field an electric current would be induced in the coil. Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators.
