Velocity of the tennis ball = ?

Solution:

Velocity of a body is the displacement per unit of time.

  Velocity  = [tex]\frac{displacement}{time}[/tex]  

So;

      Velocity  = [tex]\frac{12}{0.4}[/tex]   = 30m/s

The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm. At this point water can be solid, liquid and gas. So, option (D) is correct.

phase diagram: a graph that displays the limiting conditions for a substance's solid, liquid, and gaseous phases under changes in pressure, temperature, or another combination of variables, such as solubility and temperature.

The curves in the figure were derived from measurements taken at various pressures and temperatures, and they represent a typical phase diagram for a one-component system (i.e., one made up of a single pure chemical).

The combination of temperature and pressure at which a substance can exist in all three of its states—gas, liquid, and solid—is known as the triple point.

The Kelvin(K), the International System of Units' (SI) fundamental unit of thermodynamic temperature, is defined using the triple point of water. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm.

Answer:

5) Displacement = +3.125 m

Displacement is in the same direction as the force vector.

6) Force = -53.89 N

Force is in an opposite direction relative to the displacement.

Explanation:

5) We are given;

Force; F = 160 N.

Workdone; W = +500 J

Now, formula for workdone is;

W = Force × displacement

Thus, displacement = Work/force

Displacement = 500/160

Displacement = +3.125 m

Thus, displacement is in the same direction as the force vector.

6) We are given;

Displacement; d = 18 m.

Workdone; W = -970 J

Like in the first answer above,

Workdone = Force × Displacement

Thus;

Force = Workdone/Displacement

Force = -970/18

Force = -53.89 N

Since force is negative and displacement is positive, it means force is in an opposite direction relative to the displacement.

Answer:

1,500 km

Explanation:

300 km/h

300 kilometers PER HOUR

So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.

300 * 5 = 1,500

The train moves at 1,500 km in 5 hours.

Answer:

5.55m/s

Explanation:

The vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and  horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.

Projectile motion is an example of two dimensional motion.

Given is a ball rolls off a 1 m high table and lands on the floor 3 m away from the table.

Using the second equation of motion for the vertical motion -

S = ut + 1/2at²

S = 0 + 1/2at²

S = 1/2at²

t²= 2S/a

t² = (2 x 1)/9.8

t² = 2/9.8  

t² = 0.2040

t = 0.451

Now, the vertical velocity of the ball just before it hits the floor -

v = u + at

v = 0 + at

v = at

v = 9.8 x 0.451

[v] = 4.42 m/s

Now, using the second equation of motion for horizontal direction -

S = ut + 1/2at²

S = ut + 0

3 = u x 0.451

u = 3/0.451

[u] = 6.6 m/s

Which is also the horizontal velocity of the ball just before it hits the floor.

Therefore, the vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and  horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
