What is the volume of a stopper that has a mass of 57 grams and a density of 8.4 g/cm3?

Physics
1 answer:
nikdorinn [45]2 years ago
8 0

Answer:

Explanation:

Mass ( m) = 57 gram

density (d)= 8.4 g/cm^3

volume (v)=?

we know density is mass per unit volume

d = m/v

or v = m/d

v = 57/ 8.4

volume = 6.79 cm^3

hOPe it will help :)

pentagon [3]
The answer is 100.
The formula is KE = 1/2mv^2
Then you plug in 50 to the m
And 2 to the v . That’s how I got 100 .
Hope this helps

(a) Consider a fusion generator built to create 3.00 GW of power. Determine the rate of fuel burning in grams per hour if the DT
Stels [109]

The rate of fuel burning in grams per hour if the DT reaction is used is 1.08 ×10^1^3 J/g per hour

<h3>How is the rate of fuel burning in grams per hour calculated when the D-T reaction is used?</h3>
  • D + T → He + n
  • The D-T fusion reaction results in a Helium (He) and  neutron (n)

E = 17.59 MeV

Mass = 2.014u + 3.016u

= 5.030u

Energy per Kg = (17.59×10^6×1.6×10^-^1^9) ÷ ( 5.030×1.66×10^-^2^7)

= 3.37×10^1^4 J/Kg

= 3.0× 10^9 J/g

Rate of fuel burning in grams per hour = 3.0× 10^9 ×  3600

= 3.6×3.0×10^1^2

= 1.08 ×10^1^3 J/g per hour

If the pressure acting on a given sample of an ideal gas at constant temperature is tripled, what happens to the volume of the g
oee [108]

Answer:

Explanation:

According to Boyle's law  for constant temperature of gas Pressure is inversely proportional to the volume of gas.

PV=nRT

PV=constant

P\propto \frac{1}{V}

if Pressure is tripled then

P\times V_1=3P\times V_2

V_2=\frac{V_1}{3}

Volume becomes one-third of original volume

In order to induce electrical energy into a conductor or generator, what three factors must be present?
salantis [7]
The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.
