William Ferrel:
balu736 [363]

Answer:

William Ferrel created a tide-prediction machine.

Explanation:

  • William Ferrel create a machine in late 19th century that was the best combination of mechanical parts and computer coding.
  • It was a mechanical analog computer that could predict the ebb of tides and even the height of tides that could be irregular.
  • It was widely used for marine networks and navigation. Later on many improvisations and additional features were added on it.
  • During the world war times, this tide prediction machine was of great use for military purpose.

A spacecraft in outer space increases velocity by firing its rockets. How can hot gases escaping from its rockets change the vel
Elena-2011 [213]

Answer:

Momentum is conserved.

Explanation:

-Momentum is conserved.

-By Newton's third law (For every action, there is an equal and opposite reaction.)-the change in momentum of gases in one direction must be balanced by an equal change in momentum of the spacecraft in the opposite direction.

A car moves in a circular motion and it is subject to a centripetal acceleration of 24 m/s2. If the radius of the circular path
Softa [21]

Answer:

Explanation:

Centripetal acceleration is given by:

a_{c} = v^{2}/r

Thus, centripetal acceleration is inversely proportional to the radius. Thus, when radius will double, the centripetal acceleration will be halved.

1. What is the kinetic energy of a 1.75 kg ball travelling at a speed of 54 m/s?
Over [174]

Answer:

We conclude that the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.

Explanation:

Given

  • Mass m = 1.75 kg
  • Velocity v = 54 m/s

To determine

Kinetic Energy (K.E) = ?

We know that a body can possess energy due to its movement — Kinetic Energy.

Kinetic Energy (K.E) can be determined using the formula

K.E=\frac{1}{2}mv^2

where

  • m is the mass (kg)
  • v is the velocity (m/s)
  • K.E is the Kinetic Energy (J)

now substituting m = 1.75, and v = 54 in the formula

K.E=\frac{1}{2}mv^2

K.E=\frac{1}{2}\left(1.75\right)\left(54\right)^2

K.E=1458\times 1.75

K.E=2551.5 J

Therefore, the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.
