A car manufacturer wants to change its car’s design to increase the car’s acceleration. Which changes should the engineers consider making to the design? increase the force that the engine provides decrease the force that the engine provides increase the mass of the car decrease the mass of the car increase the top velocity the car can travel decrease the top velocity the car can travel
Answer:
I. increase the force that the engine provides.
II. decrease the mass of the car
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
[tex] Acceleration = \frac {Force}{mass} [/tex]
In this scenario, a car manufacturer wants to change its car’s design to increase the car’s acceleration. Thus, the changes the engineers should consider making to the design is to increase the force that the engine provides and decrease the mass of the car.

Answer:
Trabajo realizado = 600 Nm
Explanation:
Dados los siguientes datos;
Fuerza = 200 Newton
Distancia = 3 metros
Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia
Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3
Trabajo realizado = 600 Nm

why Newton law of gravitational force is called universal law
Answer:
Newton's law of gravitational holes good irrespective of the nature of two bodies., i.e., big or small, at all times, at all locations and for all distances in the universe.
Explanation:
It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.

What is centripetal force?
A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path.
It is "a force by which bodies are dragged or driven, or in any manner tend, towards a point as to a center," according to Isaac Newton.
Given parameters:
Mass of the Earth: M = 6.0 × 10²⁴ kg.
Mass of the moon: m = 7.3 × 10²² kg.
Moon's tangential speed: v = 1,025 m/s
Let the distance between the center of Earth and the moon is r.
Hence,
GMm/r² = mv²/r
r = GM/v²
= 6.7 × 10 ⁻¹¹ × 6.0 × 10²⁴ / (1,025)²
= 3.82×10⁸ m.
Hence, by subtracting Earth's radius = 6.4 x 10⁶ m, we get, the distance between Earth and its moon is 3.8×10⁸ m.

Name two devices we use generators in. Describe how they work.
Answer:
There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
Explanation:
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

It is chemically unreactive, it is highly radioactive and has a short half life.2) 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).Explanation:

us the formula
speed = frequency x wavelength
343 = 440 x wavelength
343 / 440 = wavelength
wavelength = 0.78 m
I think the last option, you wrote wrongly, it is supposed to be 0.78 not 0.078 .

The graph shows the amplitude of a passing wave over time in seconds (s) What is the approximate frequency of the wave shown? A. 6 Hz B. 0.2 0.4 Hz
Answer:
0.2 I took the test
Explanation:
I took the test
The time period of the whole wave cycle is 6 seconds but the time period of one complete wave is about 4 seconds here. The inverse of this time period is the frequency, that is 0.2 Hz.
What is frequency ?Frequency by definition is the number of events per unit time. Frequency of a wave is the number of wave cycles in one second. It is the inverse of the time period.
Frequency is directly related to the energy of the wave. As the frequency increases, energy of the wave also increases. In the given graph the wave cycle is given for a time of 6 seconds.
The time period for one complete wave is 4 second from the graph.
thus, T = 4 s
v = 1/T
= 1/4 = 0.2 s⁻¹ or 0.2 Hz
Therefore, the frequency of the wave shown, is 0.2 Hz.

What name is given to the turning effect of a force?
Answer:
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. When undoing a nut fastened to a screw by hand one realises that the amount of force required is a lot greater than when undoing the same nut using a spanner.

Five independent measurements are made of the diameter of a cylinder. Results, in mm, are: 21.8; 21.6; 22.1; 21.9; 22.1. What should be the reported value of the cylinder's diameter?
Answer: 21.9 mm
Explanation:
Given that five independent measurements are made of the diameter of a cylinder. Results, in mm, are: 21.8; 21.6; 22.1; 21.9; 22.1. What should be the reported value of the cylinder's diameter?
The measurement of the diameter of cylinder is measured several time in order to reduce the uncertainty called random error.
The reported value of the cylinder's diameter should be the average or the mean value of the whole measurement.
That is
Mean = (21.8 + 21.6 + 22.1 + 21.9 + 22.1) ÷ 5
Mean = 109.5 ÷ 5
Mean = 21.9 mm
Therefore, the reported value of the cylinder diameter will be 21.9 mm
