An 1.1 kW dryer is used for 30 minutes every day. What would Georgia Power charge for the month (30 days) if their going rate is 11 cent/kWhr?

Explanation:

So to calculate speed of sound in metal rods, we use this formula:

=√E/P where E = modulus

& P = Density of the substance.

Hope this helps!

Specific heat is quantity of heat required to increase the temperature of a substance by one degree celsius.

The formula to calculate heat energy is

Q=mc∆T

We know, Q=mc∆T

Where Q = heat energy

m = mass

c= specific heat capacity

∆T= change in temperature

Thus,

According to above formula

c= Q/m∆T

Here m= 2 kg

∆T= 5 degrees

Q= 2000 joules

c= 2000/2×5

c= 200

Thus, the specific heat capacity of the block is 200.

Answer:

distance =2km

time =1/2hour

speed =distance /time =2/1/2=4km/h

The average speed of the gazelle is equal to 4 Km/h. Therefore, option (C) is correct.

The average speed can be defined as the total distance traveled in a fixed interval of time. It can be determined by dividing the total distance traveled by the total time.

The average velocity of the object is a single value if the object moves uniformly, it will travel the same distance in the same interval of time.

The mathematical expression for the average speed is as follows:

The average speed = Total distance covered/Total time taken

Given, the distance traveled by gazelle = 2 Km

The time taken by the gazelle to travel this distance = 1/2 hr = 0.5 hr

The average speed = 2Km/ 0.5 hr = 4 Km/hr

Therefore, the gazelle's average speed is equal to 4 Km/hr.

Answer:

a = 0.41 [m/s²]

Explanation:

To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

F = force [N]

m = mass = 87 [kg]

a = acceleration [m/s²]

The frictional force will be taken as negative, since it opposes the movement of the block.

\(43-7.3 = 87*a\\35.7 = 87*a\\a=0.41[m/s^{2} ]\)

Explanation:

The frequency of sound waves received by the microphone influences the output or pitch of the sound obtained from the microphone.

The higher the frequency of the sound received by the microphone, the higher the output of the microphone and vice versa. This is because, the higher the frequency of sound, the higher the oscillations produced and the greater the output of the microphone.

The rise and fall in the pitch of sound waves as the frequency of sound waves varies is called inflection.

According to given data, the average speed of train is 25 km/h.

Given data,

distance = 5 km

time = 12 minutes

average speed = ?

changing time from minute to hour

So,

hour = 12 / 60

hour = 0.2

Then to calculate speed use the formula,

s = d / t

s = 5km / 0.2hr

s = 25 km/h

Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector value, whereas speed is a scalar value. It has a dimension of time-distance. As a result, the basic unit of time and the basic unit of distance are combined to form the SI unit of speed. Thus, the metre per second (m/s) is the SI unit of speed.

A person pushing a wheelbarrow, causing it to move forward, is the example that illustrates Newton's first law. The correct option is C.

Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

According to Newton's first law, a body tries to maintain its motion until or unless the external force is not applied to it.

If a body is at rest, try to rest if the body is in motion, try to be in motion until or unless an external force is not applied to it.

The weight of the box is 10 Kg. The normal force acts on the box is 83.4 N. Thus, its acceleration is 8.34 m/s² downwards.

Acceleration of a moving object is its rate of change in its velocity. Acceleration is a vector quantity thus, characterised by magnitude and direction.

According to second law of motion, force is the product of mass and acceleration.

Given the force acting on the box that it experience as the weight = 83.4 N

mass of the box = 10 Kg.

thus, acceleration  = f/ m = 83.4 N/10 kg = 8.34 m/s².

Explanation:

There are many units that are used to measure length of an object. For example centimeters, meters, millimeters etc.

There is a relationship between any of two units to measure lengths. If we want to convert some length from cm to m, it can be done as follows :

1 cm = 0.01 m

or

1 m = 100 cm

When we use this conversion, the calculation remains the same. Only the way to represent it will be different.

Hence, there is no lose of information when converted from centimeters to meters.

The average acceleration vector of the ball is approximately 9.8 m/s² downward.

When the ball is thrown upward, it experiences a constant acceleration due to gravity pulling it downward. This acceleration is equal to 9.8 m/s², which is the acceleration due to gravity near the surface of the Earth. Since the ball reaches the same speed in the downward direction when it returns to the hand, we can conclude that its average acceleration vector is also 9.8 m/s² downward.

When the ball is thrown upward, it moves against the force of gravity. As it moves upward, the gravitational force slows it down until it reaches its highest point. At this point, the ball momentarily stops before reversing direction and falling back downward.

The force of gravity then acts in the same direction as the ball's motion, causing it to accelerate downward. The acceleration due to gravity remains constant throughout the ball's motion, regardless of its direction.

When the mass of a gas is increased by adding more particles while keeping pressure and temperature constant, the volume of the gas will also increase proportionally.

According to Avogadro's law, at constant temperature and pressure, equal volumes of gases contain an equal number of particles (molecules or atoms). This implies that the volume of a gas is directly proportional to the number of particles present.

When more particles are added to a gas system while maintaining constant temperature and pressure, the total number of particles in the system increases. As a result, the volume of the gas also increases to accommodate the additional particles. The gas expands to occupy a larger space to maintain the same pressure and temperature.

This behavior can be explained by the ideal gas law, which combines Boyle's law, Charles's law, and Avogadro's law. According to the ideal gas law, PV = nRT, where P represents pressure, V represents volume, n represents the number of particles (moles), R is the gas constant, and T represents temperature.

Since, pressure and temperature are constant, increasing the number of particles (n) will cause the volume (V) to increase proportionally.
