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.

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)

Answer:
During a full moon phase, the Earth is aligned between the sun and the moon, wherein one side of the Earth is facing the sun, while the other side that faces the moon is in darkness.
In this case, when the astronaut stands in the near side of the moon, the ground is lit up due to the sun’s light that it reflects. On the other hand, the astronaut’s view of the Earth would look dark.

If a toy train has a mass of 1.5 KG and accelerates at a rate of 20 M/S 2 calculate force acting on it?
Answer:
F = 30 N
Explanation:
Given that,
Mass of a toy train, m = 1.5 kg
The acceleration of the toy-train, a = 20 m/s²
We need to find the force acting on it. We know that, net force acting on an object is given by :
F = ma
Substitute all the values,
F = 1.5 × 20
F = 30 N
Hence, the net force acting on the toy train is equal to 30 N.

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
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
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.
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]

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

Answer:
the answer is 11 N left
Explanation:
there is more force being applied in the direction left, so the ball will move left. to find the net force that the ball will move in that direction subtract the force being applied in the opposite direction. so, 16N-5N=11N. your answer in 11 N left.
