Briefly describe how the Sun produces energy.
kobusy [5.1K]

Answer:

<em>The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.</em>

A water skier is pulled by a boat traveling with a constant velocity. Which one of the following statements is false concerning
ycow [4]

Answer:

C. There is a net horizontal force on the skier in the direction the ​boat’s velocity.

Explanation:

This is because, according to Newton's First law of motion, when an object which in this case is the skier tends to be in equilibrium because it travels at a constant velocity, there is no net acceleration of the skier, and this causes the net force on the skier to be equal to zero.

Therefore in this question, option C which states that "There is a net horizontal force on the skier in the direction the ​boat’s velocity" is a false statement.

Are volcanoes fed by highly viscous magma a greater threat to life and property than volcanoes supplied with very fluid magma?
butalik [34]

Answer:

A volcano fed by highly viscous magma is likely to be a greater threat to life and property than a volcano supplied with very fluid magma because with high viscous magma gas is trapped more in the magma so the gas will build up and then eventually explode, whereas with fluid magma the gas can escape allowing the magma.

HOPE THIS HELPS!!!

The cross section of a copper strip is 1.2 mmthick and 20 mm wide. There is a 25-A current through this cross section, with the
Naily [24]

To solve this problem it is necessary to use the concepts related to the Hall Effect and Drift velocity, that is, at the speed that an electron reaches due to a magnetic field.

The drift velocity is given by the equation:

V_d = \frac{I}{nAq}

Where

I = current

n = Number of free electrons

A = Cross-Section Area

q = charge of proton

Our values are given by,

I = 25 A

A= 1.2*20 *10^{-6} m^2

q= 1.6*10^{-19}C

N = 8.47*10^{19} mm^{-3}

V_d =\frac{25}{(1.2*20 *10^{-6})(1.6*10^{-19})(8.47*10^{19} )}

V_d = 7.68*10^{-5}m/s

The hall voltage is given by

V=\frac{IB}{ned}

Where

B= Magnetic field

n = number of free electrons

d = distance

e = charge of electron

Then using the formula and replacing,

V=\frac{(2.5)(25)}{(8.47*10^{28})(1.6*10^{-19})(1.2*10^{-3})}

V = 3.84*10^{-6}V
