By increase impulse we can increase in time for the application of a given torque (e.g., 200 nm) affect angular impulse.
A force's magnitude and its line of action's angle of perpendicularity with respect to the axis of rotation are multiplied to form torque. Usually, the lowercase Greek letter tau is used to represent torque. It is typically indicated by the letter M when used as a moment of force. The term "torque" refers to the twisting force that an engine exerts when it works, and it expresses the rotational force. The use of a wrench, turning a doorknob, opening a soda bottle, or peddling a bicycle all involve torque. The equivalent of linear force in rotation is torque. The distance traveled in one unit of time is referred to as speed. Inverse proportionality describes the relationship between speed and torque.

2. electrical appliances are usually grounded in order to (a) maintain a balanced charge distribution (b) prevent the buildup of heat on them (c) run properly using household electricity (d) prevent the buildup of static charges on their surfaces
Electrical appliances are usually grounded in order to-
(a) maintain a balanced charge distribution.
What is meant by Grounding?
By transferring electrons between one thing and a larger object, a process known as grounding allows one to reduce an object's excess charge.When an object is grounded, the excess charge is reduced due to the transfer of electrons from the grounded object to the ground.
A ground is essentially an object that acts as an apparently endless source of electrons. It has the ability to send electrons to or absorb electrons from charged objects in order to neutralize such objects.
Hence, the correct option is-
(a) maintain a balanced charge distribution.

Answer: 35m/s
Explanation: answer from castle learning
A projectile is launched horizontally from a height of 65 meters with an initial horizontal speed of 35 meters pre second. projectile's horizontal speed after it has fallen 25 meters is 35 m/s.
what is speed ?Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
The formula of speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s
There are four types of speed such as Uniform speed, Variable speed, Average speed, Instantaneous speed
Uniform speed is an uniform speed when the object covers equal distance at equal time intervals, variable speed is defined as when the object covers a different distance at equal intervals of times.
Average speed is defined as the uniform speed the ratio of total distance travelled by an object to the total time taken by the object.
Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

The volleyball will reach at the maximum height at 0.673 s after it is served.The Calculating for the height the volleyball will reach before going to downwards. Therefore the volleyball will do have a maximum value of 3.07 m with respect to the ground.
3.78 m Ignoring resistance, the ball will travel upwards until it's velocity is 0 m/s. So we'll first calculate how many seconds that takes.
7.2 m/s / 9.81 m/s^2 = 0.77945s
The distance traveled is given by the formula d = 1/2 AT^2, so substitute the known value for A and T, giving
d = 1/2 A T^2 d = 1/2 9.81 m/s^2 (0.77945 s)^2 d = 4.905 m/s^2 0.607542 s^2 d = 2.979995
m So the volleyball will travel 2.979995 meters straight up from the point upon which it was launched. So we need to add the 0.80 meters initial height.

All of these forms of electromagnetic radiation or waves travel at the speed of light, the highest possible speed. The only difference between these types of electromagnetic waves is their length, or wave, or "wavelength." Another way to characterize waves is the number of waves received per second, since they all travel at the speed of light. This is the wave frequency. A specific range of radio frequencies from 1 GHz to 10 GHz, "microwaves", is particularly well suited for interstellar communications. At lower frequencies, our galaxy emits enormous amounts of radio waves, creating a large amount of background noise.

By how much does the density of air increase when it is compressed to half its volume?.
When the air is compressed to half its volume the density gets doubled.
What is density?Density refers to mass of matter per unit volume. The most common symbol for density is ρ. Density provides a convenient means of obtaining the mass of an object from its volume and vice versa. A change in the mass or volume of an object can change the density of the object. So, when volume increases density decreases simultaneously.
Since, Density = Mass/ Volume
If the volume is compressed to half i.e. V/2 then,
ρ = M/(v/2)
ρ = 2M/V

Water is referred to as a secondary refrigerant when it is cooled and circulated all through the building to higher ventilation coils.
How do secondary refrigerants work?With the help of secondary refrigerants, the quantity of primary refrigerants that are bad for the environment can be kept to a minimum and contained. In contrast to conventional refrigerants like HCFCs, secondary refrigerants, such as water, air, hydrocarbons, ammonia, and carbon dioxide, are less harmful to the environment.
Why are secondary refrigerants advantageous?The benefits of using refrigerants for industrial cooling include having a low primary refrigerant charge, preserve and enhance by limiting the use of the primary refrigerant to the engine compartment, a secondary pipe system that may occasionally be smaller, and the ability to use alternative insulations.
