What is Thunderstrom?
A thunderstorm, sometimes referred to as an electrical storm or a lightning storm, is a type of storm that is distinguished by the presence of lightning and the thunder that results from the lightning's acoustic effect on the Earth's atmosphere.
Thundershowers are the name for relatively weak thunderstorms. A cumulonimbus is a form of cloud where thunderstorms develop. They frequently produce heavy rain. and occasionally snow, sleet, or hail and they are typically accompanied by strong wind.
However, some thunderstorms result in little or no precipitation. A squall line, often known as a succession of thunderstorms, can form or become a rainband.
Therefore, When a cold, dry air mass collides with a warm, humid air mass over the land, that's a tornado, but on top of that the air rises and it cools and condenses that's a thunderstorm.

1. What are Three Things you would build differently if you were to build the rocket again?
2. What are Two Things you could do to improve the flight of your rocket?
3. What practical design advice would you give to future students building a paper rocket for the first time?
1 ; Components. Rockets consist of a propellant, a place to put propellant (such as a propellant tank), and a nozzle.
2; The aerodynamic shape of the nose cone helps prevent air from slowing the rocket. The fins help guide the rocket to fly straight. Finally, the propellant system includes a mixture of fuel and a chemical called an "oxidizer" that gives off oxygen. The fuel and oxidizer burn together to launch the rocket off the ground.
3; At supersonic speeds (faster than the speed of sound), the best shape is a narrower and sharper point. Rockets with a larger diameter have more drag because there is more air being pushed out of the way
What increase in temperature is needed to increase the length of an aluminum meterstick by 1.0 mm?
42 K
24K
Answer:
42k
Explanation:
The increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.
What is thermal expansion?Thermal expansion is the property of the matter to change its shape, size, length, volume, density etc with change in the temperature.
The thermal expansion can be calculate as,
[tex]\Delta L=aL\Delta T[/tex]
Here, [tex]L[/tex] is the original length, [tex]\Delta T[/tex] is the change in the temperature and [tex]a[/tex] is the coefficient of the expansion.
Given information-
The change in the length of the aluminum mater-stick is 1.00 mm.
Let the initial size of the aluminium mater-stick is 1.00 m or 1000 mm . The thermal expansion coefficient of aluminium is [tex](2.4\times10^{-5})[/tex] per unit Kelvin.
Put the values in the above formula as,
[tex]1=(2.4\times10^{-5})\times 1000\times\Delta T[/tex]
Solve for temperature as,
[tex]\Delta T=\dfrac{1}{(2.4\times10^{-5})\times 1000} \\\Delta T=42K[/tex]
Hence the increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

I am using the equation F=ma (force equals mass times acceleration) to solve these problems.
1. You are looking for force, and have mass and acceleration. You just plug in the values for mass and acceleration to get the force needed.
F=(15kg)(5m/s^2)
F=75N
2. Again, you are looking for force, and just need to plug in the values for mass and acceleration
F=(3kg)(2.4m/s^2)
F=7.2N
3. In this problem, you have force and mass, but need to find acceleration. To do this, you need to get acceleration alone on one side of the equation - divide each side by m. Your equation will now be F/m=a
a=(5N)/(3.7kg)
a=18.5m/s^2
I did not use significant figures. Let me know if you need to do that and need any help on that. Hope this helps!

A car is traveling at 75 m/s. 50 seconds later it is traveling at 25 m/s. What is the car’s acceleration?
Answer:
a = -1 m/s^2
Explanation:
Vi = 75 m/s
Vf = 25 m/s
t = 50 s
Plug those values into the following equation:
Vf = Vi + at
25 = 75 + 50a
---> a = -1 m/s^2

A 70mm long blockhas cross-section of 50mm by 10mm the block is subjected to forces 60KN (tension) on the 50mm by 10mm face and 110KN (Compression) on the 70mm by 10mm face Determine the force to be applied on the 70mm by 50mm face such that there is no change in volume
Answer:
970 kN
Explanation:
The length of the block = 70 mm
The cross section of the block = 50 mm by 10 mm
The tension force applies to the 50 mm by 10 mm face, F₁ = 60 kN
The compression force applied to the 70 mm by 10 mm face, F₂ = 110 kN
By volumetric stress, we have that for there to be no change in volume, the total pressure applied by the given applied forces should be equal to the pressure removed by the added applied force
The pressure due to the force F₁ = 60 kN/(50 mm × 10 mm) = 120 MPa
The pressure due to the force F₂ = 110 kN/(70 mm × 10 mm) = 157.142857 MPa
The total pressure applied to the block, P = 120 MPa + 157.142857 MPa = 277.142857 MPa
The required force, F₃ = 277.142857 MPa × (70 mm × 50 mm) = 970 kN
5. An electron is separated from a proton by a distance of 1.00 10^-10 m. What is the magnitude of the electric force between them?
Answer:
2.304 * 10^-10N
Explanation:
The magnitude of the force is expressed as;
F = kq1q2/r²
k is the coulomb constant
q1 id the charge on the electron = -1.6*10^-19C
q2 is the charge on the proton = 1.6*10^-19C
k = 9*10^9
Substitute
F = (9*10^9)*( -1.6*10^-19)( 1.6*10^-19)/(1.00 10^-10)^2
F = 9*10^9*-2.56*10^-38/1.00 10^-20
F = -23.04*10^-29/1.00 10^-20
F = -23.04 * 10^(-29+20)
F = -23.04 * 10 ^-9
F = -2.304 * 10 ^ -10N
Hence the magnitude of the electric force between them is
2.304 * 10^-10N

Please help me I don’t get how to do it!!! A ray of light has a wavelength
433 nm in water (n = 1.33). What
is its wavelength in a vacuum?
(Remember, the wavelength is longer in
a vacuum.)
(Unit = nm)
Answer:
The wavelength of the light in a vacuum is 575.89 nm
Explanation:
The given parameter in the are;
The wavelength of the ray of light in water, λ₁ = 433 nm
The refractive index of water, n₁ = 1.33
The relationship between wavelength, λ, and refractive index, 'n', is presented as follows;
λ₁·n₁ = λ₂·n₂
Where;
λ₁ and λ₂ are the wavelength of the wave within the two mediums
n₁ and n₂ are the respective refractive indices of the mediums
The refractive index of vacuum, n₂ = 1
Let λ₂ represent the wavelength of light in vacuum
Therefore, we have;
1.33 × 433 nm = 1 × λ₂
∴ λ₂ = 1.33 × 433 nm/1 = 575.89 nm
Therefore, the wavelength in a vacuum, λ₂ = 575.89 nm

Determine the force of gravitational attraction between the earth (m = 5.98 x 10^24kg)
and a 70-kg physics student, where the student is at a distance of 6.39 x 10^6 m from earth's
center.
Answer:
F = 683.8 N
Explanation:
The gravitational force of attraction between the Earth and the student is given by Newton's Law of Gravitation as follows:
[tex]F = \frac{Gm_{1}m_{2}}{r^2}[/tex]
where,
F = Force = ?
G = Universal gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
m₁ = mass of Earth = 5.98 x 10²⁴ kg
m₂ = mass of student = 70 kg
r = distance between Earth and student = 6.39 x 10⁶ m
Therefore,
[tex]F = \frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^1)(5.98\ x\ 10^{24}\ kg)(70\ kg)}{(6.39\ x\ 10^6\ m)^2}\\[/tex]
F = 683.8 N
the body of mass 17 kg is attached to a string of length of 3.4 m is whirled round in vertical circle .if the tension in the string at the lowest point is 300N .calculate the speed of the body
The body is accelerating upward toward the center of the circle it traces out with magnitude
a = v ² / R
where
v = linear speed of the body
R = 3.4 m = radius of the circle it traces/length of the string
The only forces acting on it at the lowest point are the tension T of the string pulling upward on the body and weight W = mg of the body pulling it downward. By Newton's second law, we have
∑ F = T - mg = ma
Replace the acceleration with the expression from earlier and solve for v :
300 N - (17 kg) g = (17 kg) v ² / (3.4 m)
v ² = ((3.4 m) 300 N - (17 kg) g) / (17 kg)
v = √[ ((3.4 m) 300 N - (17 kg) g) / (17 kg) ]
v ≈ 5.16527 m/s ≈ 5.2 m/s
Now see if you can tell the difference between inertia and momentum. How could you change the momentum of a
moving car?
Explanation:
Inertia is the measure of the mass of an object. It is the tendency of an object to change the direction of an object.
Momentum is the product of mass and velocity. When an object having mass m moves with a particular velocity it will have momentum.
If the speed of an object is changed from u to v, its momentum can be changed and it can be calculated as :
Δp = m(v-u)
Hence, this is the required solution.
