Answer: Explanation:

If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration will be halved .

In Newton’s second law, if the net force acting on object doubles then either acceleration is double or mass is double.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

According to Newtons second law force is product of mass and acceleration.

F = ma

In Newton’s second law, if the net force acting on object doubles then either acceleration is double or mass is double.

Answer:

To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)

To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)

To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)

To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

Answer:

B

Explanation:

As we all know,mass is the amount of substance a body contains. So because Ice's mass is less than water, that's why it's able to float. In other words,we say ice is less dense than water

A volume of ice has less mass than the same volume of water. Hence, ice floats in water. Option (C) is correct.

The density of a material indicates the density of that material in a specific area. The density of a material is defined as its mass per unit volume. Density is a measurement of how closely matter is packed together. It is a distinct physical property of a specific object.

Archimedes, a Greek scientist, discovered the density principle. If you know the formula and understand the units, calculating density is simple. Density is represented by the symbol ρ, which can also be represented by the letter D.

Now, ice has less density compare to water. So, a certain volume of ice has less mass than the same volume of water. Hence, option(C) is correct.

Answer:

The 2 forces are a Push and a Pull

Mass is the resistance of change in speed or position when adding force.

Weight is the force of gravity

Tension Force is the pulling force transmitted through a string cable or chain. The formula for this is T = mg + ma.

It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.

An unbalanced force is when there is 2 forces on opposites of an object both are adding force but one side is stronger than the other.

Friction is a force that heats things up. This happens when we rub our hands together and the heat that is generated from the friction makes our hands warmer.

Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion.

Answer:

a. Winter.

Explanation:

Answer:

Winter

Explanation:

Answer:

θ = 29.38°

Explanation:

The centripetal force is given by the formula;

F_c = F_n(sin θ) = mv²/r

Now, the vertical component of the normal force is; F_n(cos θ)

Now, this vertical component is also expressed as; F_n(cos θ) = mg

Thus, the slope is;

F_n(sin θ)/F_n(cos θ) = (mv²/r)/mg

tan θ = v²/rg

v² = rg(tan θ)

The initial speed will be gotten from the relation;

(v_o)² = μ_s(gr)

Plugging rg(tan θ) for (v_o)², we have;

μ_s(gr) = rg(tan θ)

rg will cancel out to give;

μ_s = (tan θ)

Thus, θ = tan^(-1) μ_s

μ_s is coefficient of static friction given as 0.563

θ = tan^(-1) 0.563

θ = 29.38°

Answer:

normal force= 480.2 x component=477.4  y component= 110.4

Explanation:

I'm sorry I just did this today in class but i think normal force has to be equal to mg or the mass * gravity of the person and that would be 480.2 newtons. I multiplied 9.8 (gravity) by the mass of 49g

I think for the x and y components you can make a triangle with the angled string and then use sohcahtoa to solve for the tension. I used cos(13) = x/490 to solve for x component and then I used the pythagoran theroem to get the remaining side which would be : a^2 + 477.4^2 = 490^2

hope this can help and that it is correct. good luck

The magnitudes of the x- and y- components of the tension is 477.44N and 110.23N

The normal force acting on the skier is 480.2N

The magnitude of the x- and y- components of the tension is expressed as:

Given the following

Tension T = 490N

x = 490 cos13° = 477.44N

y = 490sin13° =  110.23N

Hence the magnitudes of the x- and y- components of the tension is 477.44N and 110.23N

The normal force acting on the skier is equal to the weight.

N = W = mg

N = W = 49 * 9.8

N = W = 480.2N

Hence the normal force acting on the skier is 480.2N

Explanation:

Answer:

As frequency (cycles per second) increases the wavelength decreases.

As frequency increases the period also decreases

If wave speed or velocity increases, so too does the frequency

Amplitude of a wave is totally independent of frequency, period etc.  So it remains the same as frequency shifts.  Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.

Explanation:

F= 1/t  Frequency is inversely proportional to time (wavelength)

Period is the time it takes for one wave cycle to complete   Period is 1/f

++++++++++++++++++++++++++++++++++++

vw=λT  Speed of propagation vw= wavelength x T time

vw=fλ  Knowing frequency multiply times wavelength to get wave speed.

++++++++++++++++++++++++++++++++

Amplitude varies only as the energy applied varies.  Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared  or .707 of the peak of the waveform).
