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

14.0.5 cm 13. wind speed surface area temperature

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!

Answer:

lowkeyyyy

explanation:

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.

hi..

its option C..

cuz everyone is equal before the law.. and no one an be discriminated on the basis of their gender, religion, caste, race, colour or anything!..

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:

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.

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.

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.

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

Answer:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity.

Explanation:

Answer:

The volume is the same apply this formula Pv=nRT shows direct proportionality this is what shows so we can take only PV=T and v stays the same.

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

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
