2. Find the electrostatic force between two protons that are 2.0 m apart. The elementary charge of
a proton is 1.602 x 10-19 C.
Answer:
the electrostatic force between the two protons is 5.775 x 10⁻²⁹ N.
Explanation:
Given;
charge of protons, q = 1.602 x 10⁻¹⁹ C
distance between the two charges, r = 2.0 m
The electrostatic force between the two protons is calculated as;
[tex]F = \frac{kq^2}{r^2}[/tex]
where;
k is coulomb's constant, = 9 x 10⁹ Nm²/C²
[tex]F = \frac{(9\times 10^9)(1.602 \times 10^{-19})^2}{(2)^2} \\\\F = 5.775 \times 10^{-29} \ N[/tex]
Therefore, the electrostatic force between the two protons is 5.775 x 10⁻²⁹ N.
The force between the two protons separated by the distance of 2 m will be [tex]F=5.775\times 10^{-29}\ N[/tex]
What is coulomb's force?The coulomb's force is defined as when two charged particles are separated by the distance r and having charge q then the force will be directly proportional to the product of the charges and inverse to the distance between them.
The coulomb's force will be given by
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
Here it is given that
Charge on the proton=[tex]q=1.602\times 10^{-19}\ C[/tex]
The distance between protons = 2 m
The value of constant [tex]k=9\times 10^{-29}\ \dfrac{Nm^2}{C^2}[/tex]
Putting the values in the formula
[tex]F=\dfrac{(9\times 10^9) (1.602\timeds 10^{-19}^)^2}{2^2}[/tex]
[tex]F=5.775\times 10^{-29}\ N[/tex]
Hence the force between the two protons separated by the distance of 2 m will be [tex]F=5.775\times 10^{-29}\ N[/tex]

An electron (e = 1.6 x 10-19 C) is traveling at 4.00 x 107 m/s due North in a horizontal plane through a point where the earth’s magnetic field has a component to the North of 2.00 x 10-5 T and a downward (in to the earth) of 5.00 x 10-5 T. Calculate the magnetic force (magnitude and direction) on the electron and its acceleration. Me = 9.11 x 10-31 kg
Answer:
Explanation:
Force on the electron due to magnetic field 's north component will be zero because both velocity of electron and direction of magnetic field are same .
Force due to downward component of magnetic field
= B q v where B is magnetic field , q is charge moving and v is velocity of charge
F = 5 .00 x 10⁻⁵ x 1.6 x 10⁻¹⁹ x 4 x 10⁷
= 32 x 10⁻¹⁷ N
acceleration = F / m where m is mass of electron
= 32 x 10⁻¹⁷ / 9.11 x 10⁻³¹
= 3.5 x 10¹⁴ m/s²

Using Ohms Law, calculate the current that would exist in a circuit having a voltage of 240V experiencing 110 Ohms of resistance
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)

Essay on global temperature change. I have tried to do this multiple times but it always end up all scrambled so if someone would write on for me that would be amazing
Global climate change is a change in the atmosphere that occurs all over the planet simultaneously. Although these changes have occurred in certain periods in a natural way, we are currently facing global climatic changes caused by human activities, which have inconsequentially modified the natural harmony of climatic conditions.
The climate change we are currently experiencing refers to global warming, where the earth's temperature is increasing on an alarming and worrying scale. Global warming has caused the melting of the polar ice caps, harmed marine life, increased the surface temperature of the oceans, caused droughts and floods, in addition to promoting an abnormal and harmful sensation to living beings.
These changes are the result of the constant use of fossil fuels, deforestation, pollution and other human activities that have degraded nature and the atmosphere. This is because these activities, mainly the use of fossil fuels, promote a large production of carbon dioxide, which, when released into the atmosphere, causes holes in the ozone layer that protects our planet from the sun's rays. With the depletion of the ozone layer, the planet is left unprotected and receives sun rays at harmful intensities.
Therefore, we can conclude that the global climate changes that we are experiencing are the consequences of our own actions and that is why it is our responsibility to repair the damage caused by global warming and to promote measures that reduce it.
A heat pump receives heat from a lake that has an average winter time temperature of 6o C and supplies heat into a house having an average temperature of 25o C. (a) If the house loses heat to the atmosphere at the rate of 60,000 kJ/h, determine the minimum power supplied to the heat pump (in kW) that can maintain the interior temperature of the house at 25o C. (b) Suppose the heat pump absorbs energy from the ground (10o C) instead of the lake, Calculate the minimum power (in kW) required for the heat pump.
Answer:
Explanation:
60000 kJ / h = 60000 x 1000 / (60 x 60 )
= 16667 J /s
a)
[tex]\frac{Q_H}{W} =\frac{T_H}{T_H-T_C}[/tex]
where [tex]Q_H[/tex] and [tex]W[/tex] are heat supplied and heat given from outside source .
Here [tex]Q_H[/tex] = 16667 J/s
[tex]\frac{T_H}{T_H-T_C}=\frac{298}{298-279}[/tex]
= 15.684
[tex]Q_H = 16667 J/s[/tex]
16667 / W = 15.684
W= minimum power supplied = 1062.7 W.
b )
If [tex]T_C=283K[/tex]
[tex]\frac{T_H}{T_H-T_C}=\frac{298}{298-283}[/tex]
=19.87
[tex]\frac{Q_H}{W} = 19.87[/tex]
[tex]W=\frac{Q_H}{19.87}[/tex]
[tex]W=\frac{16667}{19.87}[/tex]
= 838.8 W .

Explanation:
A baseball is struck home plate and acquires a speed of 60m/s. It rises to a height of 100.0 m above its starting level. Find its speed at the height
Answer:
40 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 60 m/s
Height (h) = 100 m
Acceleration due to gravity (g) = 10 m/s²
Final velocity (v) =?
The velocity at height 100 m can be obtained as follow:
v² = u² – 2gh (since the ball is going against gravity)
v² = 60² – (2 × 10 × 100)
v² = 3600 – 2000
v² = 1600
Take the square root of both side
v = √1600
v = 40 m/s
Thus, velocity at height 100 m is 40 m/s
Indigo the dog has escaped. She trots north at 5m/s. She looks behind to see Miss Leuthauser chasing after her and then she starts running at 15m/s. She changed her velocity in 2 seconds. What is her acceleration?
Answer:
5 m/s²
Explanation:
From the questio,
Acceleration (a) = Change in velocity(Δv)/time(t)
a = Δv/t
a = (v-u)/t.................. Equation 1
Where v = final velocity, u = initial velocity, t = time
Given: v = 15 m/s, u = 5 m/s, t = 2 seconds
substitute these value into equation 1
a = (15-5)/2
a = 10/2
a = 5 m/s².
Hence her accleration is 5 m/s²

How many seconds will elapse between seeing lightning and hearing the thunder if the lightning strikes 1mi (5280 ft) away and the air temperature is 90.0°F?
Answer:
t = 4.58 s
Explanation:
In this problem, we need to find the time elapse between seeing lightning and hearing the thunder if the lightning strikes 1mi (5280 ft) away and the air temperature is 90.0°F.
T = 90.0°F = 32.2 °C
The speed of sound at temperature T is given by :
v = (331.3 +0.6T)
Put T = 32.2°C
So,
v = (331.3 +0.6(32.2))
= 350.62 m/s
We have, distance, d = 1 mile = 1609.34
So,
[tex]t=\dfrac{d}{v}\\\\t=4.58\ s[/tex]
So, the required time is equal to 4.58 seconds.

Which of the following best describes why tidal energy is considered a renewable energy resource? A. The Moon receives energy from the Sun, which is a renewable resource. B. Humans can create more tidal energy by setting up more tidal energy plants. C. Ocean water will never be exhausted. D. Tidal energy is replaced naturally by the Moon's gravity.
Answer:
D. Tidal energy is replaced naturally by the Moon's gravity.
Explanation:
The reason tidal energy is considered a renewable energy resource is that Tidal energy is replaced naturally by the Moon's gravity. The Moon's gravity creates bulges on the side of Earth that is closest and farthest from the Moon. These bulges also pull water causing high tides in those areas. As the Earth rotates these areas experience low tide while the areas that had low tide now experience high tide. This constant shift creates tidal energy every day, which is replenished naturally.
