explanation

When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.

heat energy = (mass of substance)(specific heat)(change in temperature)

Q = mc∆T

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆ is a symbol meaning "the change in"

∆T = change in temperature (Kelvins, K

Answer:

.737 v

Explanation:

Since they are in series....they all have the same current running through them.....find the total resistance to calculate the current:

R = 67 + 83 + 433 + 309 = 892 ohm

V/R = current = 7.92 / 892 = 8.87 mAmps

Now the voltage across ecah resistor is   I R

 for the second one   8.87 ma * 83 ohm = V = .737 V

Answer:

An object that weighs 20 kg

Explanation:

Acceleration and mass are indirectly proportional.

The total energy available during the collision of the two protons is determined as 900,938 MeV.

Based on the principle of conservation of energy, the total energy of the two protons during the collision will be conserved.

Available energy = Er + K

Where;

Available energy = 938 MeV + 900 GeV

Available energy = 938 Mev + 900 x 10³ MeV

Available energy = 938 MeV + 900,000 MeV

Available energy = 900,938 MeV

Answer:

The x - component of the normal force is equal to 1706.45 N.

Explanation:

To solve the problem, and since there is no additional information, we can safely assume that the x-axis is parallalel to the hill surface and the y-axis is perpendicular to the x-axis. Knowing that, we can calculate the components of the normal force (or weight for this case), using the following formulas:

[tex]N

x

=W∗Sin(α)=mg∗Sin(α)[/tex]

[tex]N

y

=W∗Cos(α)=mg∗Cos(α)[/tex]

Now, using the given information, we have:

[tex]mass=m=1150Kg[/tex]

[tex]a=8.70[/tex]

[tex]g=9.81 \frac{m}{ {s}^{2} } [/tex]

Calculating, we have:

[tex]N_{x}=mg*Sin(\alpha)[/tex]

[tex] \: \: \: \: \: \: \: \: \: N_{x}=1150Kg*9.81\frac{m}{s^{2}}*Sin(8.70\°)[/tex]

Why is the moon’s force of gravity less than that of the earth?

Since the moon has a smaller mass than the earth, the moon has less gravity than the earth. Gravity is related to mass.

Larger mass = larger gravity

Smaller mass = lesser gravity

Moon has small mass, therefore less gravity.

Explanation:

Amplitude is the height of the wave from the midline to the crest

If air resistance is ignored, the ball could land on the green after a flight time of 3.5s.

The vertical velocity of the ball is calculated as follows;

[tex]h = v_yt - \frac{1}{2} gt^2\\\\7.5 = (3.5)v_y - \frac{1}{2}(9.8)(3.5)^2\\\\ 7.5 = 3.5v_y - 60.025\\\\3.5v_y = 67.525\\\\v_y = 19.29 \ m/s[/tex]

X = Vxt

Vx = (X)/t

Vx = (70)/3.5

Vx = 20 m/s

v = √(Vy² + Vx²)

v = √(19.29² + 20²)

v = 27.79 m/s

tanθ = (Vy)/(Vx)

tanθ = (19.29)/(20)

tanθ = 0.9645

θ = 43.96⁰

The time of flight is calculated as follows;

[tex]T = \frac{2u \times sin(\theta)}{g} \\\\T = \frac{2 \times 27.79 \times sin(43.96)}{9.8} \\\\T = 3.9 \ s[/tex]

X = VxT

X = 20 x 3.9

X = 78 m

The ball will land on green which is at 70 m after 3.5s.

Thus, if air resistance is ignored, the ball could land on the green after a flight time of 3.5s.

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

[tex]v=f\times\lambda[/tex]

Here, (f) is the frequency and (λ) is the wavelength.

The frequency is inverse of time. Thus, the value of frequency in time t is,

[tex]f=\dfrac{1}{t}\\f=\dfrac{1}{4}\\f=0.25[/tex]

The speed of the wave is 0.5 m/s. Put the values in the formula,

[tex]v=f\times\lambda\\0.5=0.25\times\lambda\\\lambda=\dfrac{0.5}{0.25}\\\lambda=2[/tex]

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

A uniform magnetic field is perpendicular to the plane of a circular loop. The rate must the magnitude of change to induce a 10 A current in the loop.

The magnetic field which doesn't change with respect to time is called the uniform magnetic field.

The resistance of the loop is related to the length of the wire as

R=ρ L/ A

Diameter of wire is 10 cm formed from wire of diameter 2.5 mm and resistivity is 1.69×10⁻⁸ Ω⋅m.

Substituting the values into the above equation, we get

R ​ = {(1.69×10−8Ω⋅m) × π(0.10m)} / {π(2.5×10−3m)2/4}

R ​ =1.1×10−3Ω

Current is related to emf as

i=∣ε∣/R

=∣dΦB​/dt∣ / R

=(πl2/R) ∣ dB/dt ∣.

Substituting the given values from the question, we have rate of change of magnetic field

∣dB / dt∣​ = πr2iR​

∣dB / dt∣​ = π(0.05m)2(10A)(1.1×10−3Ω)
