Increase the Force provided by the Engine.

Decrease the Mass of the Car.

Increase the top velocity the Car can travel.

Explanation:

A design targeted at increasing the engine force, decreasing the mass of the car and increasing the top velocity will increase the acceleration of the car.

From newton's second law, we know that force is the product of mass and acceleration.

 Force = mass x acceleration

  Acceleration = \frac{force }{mass}

Acceleration is the change in the velocity of a body with time.

  • We see that acceleration is directly related to force. As the force of the engine increases, its acceleration increases.
  • But acceleration is inversely related to mass. The more the mass of the car, the lesser the acceleration. The car should be made lighter.
  • The top velocity is the maximum velocity the car can go.
  • The higher the top level velocity, the more the acceleration a car can have.

Which machine can create images of atoms?
Svetradugi [14.3K]

Answer: Scanning Tunneling Microscope

Explanation:

The answer is, of course, the greatest Star Trek fan art imaginable: images literally built out of individual atoms. The images are the work of IBM scientists who created the unique artwork with a two-ton machine called the Scanning Tunneling Microscope that moves single atoms across a tiny piece of copper.

A body of mass 8 kg moves in a (counterclockwise) circular path of radius 10 meters, making one revolution every 10 seconds. You
Sav [38]

Answer:

Centripetal force is equal to 31.55 N

Explanation:

We have given mass of the body m = 8 kg

Radius of the circular path r = 10 m

It is given that it makes 1 revolution in 10 seconds

Distance traveled in 10 seconds is equal to d=2\pi r=2\times 3.14\times 10=62.8m

Velocity is equal to velocity=\frac{distance}{time}=\frac{62.8}{10}=6.28m/sec

We have to find the centripetal force

Centripetal force is equal to F=\frac{mv^2}{r}=\frac{8\times 6.28^2}{10}=31.55N

So centripetal force will be equal to 31.55 N

A mass of 100kg is acted on by a 400N force acting vertically upward and a 600N force acting at a 45 degrees angle.Calculate the
slava [35]

Answer:

A 1.56    see below

Explanation:

I will assume the 45 degree force is upward

vertical component =   600 sin 45 = 424.26 N

 added to the other vertical force will total 824.26 N

    F = ma

   824.26 = 100 * a    shows a = 8.24 m/s upward

Now we have to assume the mass is ALSO acted on by gravity and this value is given as  9.8  ( so downward is positive)

9.81 -   8.24      =  1.56 m/s^2
