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.

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.

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.

A force of 900 N pushes a wedge 0.10 m into a log. If the work done on the log is 50 J, what is the efficiency of the wedge?
HELPPPP
Answer:
55.56%
Explanation:
We'll begin by calculating the work done in pushing the wedge. This can be obtained as follow:
Force (F) = 900 N
Distance (s) = 0.1 m
Workdone (Wd) =..?
Wd = F × s
Wd = 900 × 0.1
Wd = 90 J
Finally, we shall determine the efficiency. This can be obtained as follow:
Work output = 50 J
Work input = 90 J
Efficiency =?
Efficiency = work output / work input
Efficiency = 50 / 90 × 100
Efficiency = 55.56%
Thus, the efficiency is 55.56%

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.

How long will it take for a basketball spinning on someone’s finger to stop if it undergoes and angular acceleration of -0.15 rad/s and is traveling at 27 rad/s initially? How many revolutions will it make?
The basketball's angular velocity ω at time t is
ω = 27 rad/s + (-0.15 rad/s²) t
It comes to a stop when ω = 0, which happens for
0 = 27 rad/s - (0.15 rad/s²) t
t = (27 rad/s) / (0.15 rad/s²)
t = 180 s
In this time, the ball would undergoes an angular displacement θ of
θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²
Plug in t = 180 s and solve for θ :
θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad
One complete revolution corresponds to a turn of 2π rad, so the ball makes
(2430 rad) / (2π rad/rev) ≈ 386.747 rev
or about 387 revolutions as it slows down.

A wave frequency of 440 Hz travels through a medium at 343 m/s. Calculate the wavelength
for this wave.
150,920 m
1.28 m
97 m
0.078 m
Answer:
0.78 m
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 .
if you think I am wrong please do tell me, I will redo this.

what is the physical properties of radon
Answer:
1) Radon is colorless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow phosphorescence. 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:
