Answer:
Acceleration
Explanation:
The advertisement is describing the acceleration of the car.
Acceleration is the rate of change of velocity per unit of time. It can be expressed mathematically as;
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Any quantity that specifies the rate of change of velocity of a body within a given time frame is describing its acceleration.
If a ball is thrown alt 96 m/s, and it travels 3 seconds, what is the total distance the ball travelec
Answer: 288 m
Explanation: 288 m is the correct answer because the question states that the ball is thrown at 96 m every second, and our question tells us that the ball travels 3 seconds. This means we have to multiply 96 x 3 = 288 m.
Answer:
288
Explanation:
If the acceleration is 600m/s/s and the mass is 300kg, calculate the for the force
Answer:
180000N
Explanation:
Given parameters:
Acceleration = 600m/s²
Mass = 300kg
Unknown:
Force = ?
Solution:
From Newton's second law of motion;
Force = mass x acceleration
Force = 300 x 600 = 180000N

Una bombilla de incandescencia tiene un filamento de wolframio cuya resistividad es de 5,6 por 10 a la -8 m , su longitud es de 200 cm y su sección es de 8,0 por 10 a la -7 malcuadrado ¿resistencia?
Answer:
R = 0.14 Ω
Explanation:
The resistance of a metal is given by the relation
R = [tex]\rho \frac{L}{A}[/tex]
where ρ the resistivity is 5.6 10-8 Ω m, they also give the length and the cross section (area)
Let's reduce the magnitudes to the SI system
L = 200cm (1m / 100cm) = 2.00m
A = 8.0 10⁻⁷ m²
let's calculate
R = 5.6 10⁻⁸ [tex]\frac{2.00}{8.0 \ 10^{-7} }[/tex]
R = 1.4 10⁻¹ Ω
R = 0.14 Ω

A force of 2.0 × 102 newtons is applied to a lever to lift a crate. If the mechanical advantage of the lever is 3.43, what is the weight of the crate? A. 2.0 × 102 newtons B. 58 newtons C. 6.9 × 102 newtons D. 7.1 × 102 newtons
Answer:
C. [tex]6.9\times 10^2\ \text{N}[/tex]
Explanation:
[tex]\text{Supplied force}=2\times 10^2\ \text{N}[/tex]
M = Mechanical advantage = 3.43
Mechanical advantage is given by
[tex]M=\dfrac{\text{Weigh of crate}}{\text{Supplied force}}\\\Rightarrow \text{Weigh of crate}=M\times \text{Supplied force}\\\Rightarrow \text{Weigh of crate}=3.43\times 2\times 10^{2}\\\Rightarrow \text{Weigh of crate}=6.86\times 10^2\ \text{N}\approx 6.9\times 10^2\ \text{N}[/tex]
The weight of the crate is [tex]6.9\times 10^2\ \text{N}[/tex].

A horizontal force of 0.9N act on a body of mass 0.1kg there is resistance of 0.15 Newton opposing the first Force what acceleration will be produced please help
Answer:
a = 7.5 [m/s²]
Explanation:
To solve this type of problem we must remember Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
∑F = sum of forces [N]
m = mass = 0.1 [kg]
a = acceleration [m/s²]
Now replacing:
[tex]0.9-0.15=0.1*a\\a=7.5 [m/s^{2} ][/tex]

A crane lifts a 1000 newton pallet 30 meters. How much work does the
crane do on the pallet? Include units in your answer but no decimal point
or digits to the right of the decimal point. *
Answer:
Workdone = 3000Nm
Explanation:
Given the following data;
Force, F = 1000 N
Distance, d = 30 m
We know that workdone is given by the formula;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 1000 * 30
Workdone = 3000Nm
The middle-C hammer of a piano hits two strings, producing beats of 1.60 Hz. One of the strings is turned to 250.00 Hz. What frequencies (in Hz) could the other string have? (Answer to the nearest 0.1 Hz.)
Answer:
248.5Hz or 251.5Hz
Explanation:
Given :
Beat frequency, Fbeat = 1.5 Hz
Frequency of string 1, f1 = 250 Hz
Frequency of string 2, f2 =?
Recall:
Fbeat = |f1 - f2|
1.5 = 250 - f2
f2 = 250 - 1.5
f2 = 248.5 Hz
OR
- Fbeat = |f1 - f2|
- 1.5 = 250 - f2
f2 = 250 + 1.5
f2 = 251.5 Hz
Hence, the two possible frequencies of the other string are 248.5Hz or 251.5Hz

Which Energy is missing in the windmill energy transformation?
Wind> _________> Electrical
1.Solar
2.Light
3.Mechanical
4.Sound
Answer:
3.mechanical is the answer
Mechanical energy is missing in the windmill energy transformation.
Wind> Mechanical> Electrical. Hence option (3) is correct.
What is Wind energy?The process of using the wind to produce mechanical or electrical energy is known as wind power or wind energy. The kinetic energy of the wind is transformed into mechanical power by wind turbines. This mechanical energy can be used to particular activities (such pumping water or grinding grain) or can be transformed into electricity by a generator.
When the project size is created to match the energy requirements of the load while simultaneously monetizing economies of scale and equipment track record, wind turbine economics are maximized. A modest turbine (usually less than 10 kW) that can produce the amount of electricity needed by a residence for daily operation is needed for residential onsite energy consumption.

A 10 kilogram radio controlled airplane at 1000 meters has 100,000
joules of potential energy, and moving at 10 meters per second it has 500
joules of kinetic energy. How much mechanical energy does the radio
controlled airplane have? Include units in your answer but no decimal
point or digits to the right of the decimal point. *
Answer:
The mechanical energy of the airplane is 100,500 joules
Explanation:
The given parameters are;
The mass of the airplane = 10 kg
The height at which the airplane is located = 1000 meters
The potential energy of the airplane, P.E. = 100,000 joules
The speed of the airplane = 10 m/s
The kinetic energy of the airplane, K.E. = 500 joules
The Mechanical Energy, M.E. = The Potential Energy, P.E. + The Kinetic Energy, K.E.
M.E. = P.E. + K.E.
∴ M.E. = 100,000 joules + 500 joules = 100,500 joules
The mechanical energy of the airplane, M.E. = 100,500 joules.
