Anna [14]

Answer:

1. Magnetic force = 4.56*10^-12 N

2. Acceleration = 5.01 *10^18 m/s^2

3. A) The direction of the moving electron will change but its speed will remain constant.

Explanation:

Given Data:

B = 0.0040 T North

q = 1.6*10^-19 C

Mass of electron = 9.1*10^-31 kg

V = 9.5% of speed of light

= 9.5% *3*10^8

= 28.5*10^6 m/s west

So, B and v are perpendicular to each other.

Therefore, ∅ = 90°

1, Calculating the magnetic force using the formula;

F = qvBsin∅

= 1.6*10^-19 * 28.5*10^6*sin90

= 4.56*10^-12 N

Therefore, the strength of the force = 4.56*10^-12 N

2. Calculating acceleration using the formula;

F = ma

a = F/m

= 4.56*10^-12 /9.1*10^-31

= 5.01 *10^18 m/s^2

3. A) The direction of the moving electron will change but its speed will remain constant.

A lightning flash releases about 1010J of electrical energy. Part A If all this energy is added to 50 kg of water (the amount of

zavuch27 [327]

Answer:

water is in the vapor state,

Explanation:

We must use calorimetry equations to find the final water temperatures. We assume that all energy is transformed into heat

E = Q₁ + $Q_{L}$

Where Q1 is the heat required to bring water from the current temperature to the boiling point

Q₁ = m $c_{e}$ ( $T_{f}$ -T₀)

Q₁ = 50 4180 (100 - 37)

Q₁ = 1.317 10⁷ J

Let's calculate the energy so that all the water changes state

$Q_{L}$ = m L

$Q_{L}$ = 50 2,256 106

$Q_{L}$ = 1,128 10⁸ J

Let's look for the energy needed to convert all the water into steam is

Qt = Q₁ + $Q_{L}$

Qt = 1.317 107 + 11.28 107

Qt = 12,597 10⁷ J

Let's calculate how much energy is left to heat the water vapor

ΔE = E - Qt

ΔE = 10¹⁰ - 12,597 10⁷

ΔE = 1000 107 - 12,597 107

ΔE = 987.4 10⁷ J

With this energy we heat the steam, clear the final temperature

Q = ΔE = m $c_{e}$ ( $T_{f}$ -To)

( $T_{f}$ -T₀) = ΔE / m $c_{e}$

$T_{f}$ = T₀ + ΔE / m $c_{e}$

$T_{f}$ = 100 + 987.4 10⁷ / (50 1970)

$T_{f}$ = 100 + 1,002 10⁵

$T_{f}$ = 1,003 10⁵ ° C

This result indicates that the water is in the vapor state, in realizing at this temperature the water will be dissociated into its hydrogen and oxygen components
