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
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.

tin shear have longer handles than than the scissor used to cut cloth give reason
Answer:
For scissor, small movement at effort(at handle) should make long movement of load arm , so that it can cut longer lengths of cloth/paper. Hence blades are longer than handle.so its handle(load arm) is made longer than its blades.

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]

This force is a pull between all objects. It is the force that gives us weight here on Earth. And, if we throw a rock off of a cliff, it is the force that causes the rock to fall to Earth. What is this force?
Answer:
Gravity.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
This ultimately implies that, this force is a pull between all objects. It is the force that gives us weight here on Earth. And, if we throw a rock off of a cliff, it is the force that causes the rock to fall to Earth.

Explanation:
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
Answer:
Speed of the body = 5.1652 m/s
Explanation:
Given:
Mass M = 17 kg
Length of string = 3.4 m
Tension in the string = 300N
Find:
Speed of the body
Computation:
T - mg = mv² / R... [R = L]
So,
T - mg = mv² / L
300 - 17[9.8] = [17][v]² / [3.4]
133.4 = [17][v]² / [3.4]
v² = 26.68
Speed of the body = 5.1652 m/s

Answer these questions please and you will get the brain list
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!

The pilot directs the aircraft to fly due north at 600km/h. A side-wind blows at
100km/h towards the east. What will be the aircraft's resultant velocity? (Give both its
speed and direction)
Answer:
678.2 km/h and 80.54° north of east
Explanation:
From the question,
Using pythagoras theorem,
a² = b²+c²..................... Equation 1
Where a = resultant velocity
Given: b = 600 km/h, c = 100 km/h
Substitute these values into equation 1
R² = 600²+100²
R² = 360000+10000
R² = 460000
R = √460000
R = 678.2 km/h.
And the direction is
tanθ = 600/100
tanθ = 6
tanθ = 6
θ = tan⁻¹(6)
θ = 80.54°.
Hence the resultant velocity of the aircraft is 678.2 km/h and 80.54° north of east

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
Answer: 576

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

Choice-B is a relevant statement, although we can't see enough of the picture to actually know what's going on.
A good example of this scenario is our own moon. Because of the Sun's gravitational influence, the Moon's orbit around the Earth is not a circle or an ellipse.
