What is the pressure exerted by a column of fresh water 10m high<br>(p=1000kg/m3 and g=10m/s)​
alexira [117]
  • Height (h) = 10 m
  • Density (ρ) = 1000 Kg/m^3
  • Acceleration due to gravity (g) = 10 m/s^2
  • We know, pressure in a fluid = hρg
  • Therefore, the pressure exerted by a column of fresh water
  • = hρg
  • = (10 × 1000 × 10) Pa
  • = 100000 Pa

<u>Answer</u><u>:</u>

<u>1000</u><u>0</u><u>0</u><u> </u><u>Pa</u>

Hope you could understand.

Gekata [30.6K]

Answer:

Yes, upward

Explanation:

We can solve the problem by using Newton's second law, which can be written as

\sum F = ma

where \sum F is the net force, m is the mass, a is the acceleration.

At the beginning, the skydiver is falling at constant speed (called terminal velocity): this means that the two forces acting on him/her, the weight W (downward) and the air resistance R (upward) are equal in magnitude, and so the net force (and the net acceleration) is zero:

R-W=ma=0 \rightarrow R-W

When the parachute is opened, the resistance  force suddenly increased (because the surface area of the body increases), so Newton's second law becomes:

R-W=ma

this time, R>W, therefore a>0, which means that the acceleration has the same direction as the air resistance (upward). As a result, the skydiver will accelerated upward, which means that its vertical velocity will decrease in magnitude (because he/she was travelling downward, so the acceleration is in the opposite direction).

The potential difference between the plates of an ideal air-filled parallel-plate capacitor with a plate separation of 6.0 cm is
Yanka [14]

Answer:

1000 N/C

Explanation:

Potential difference, V = 60 V

Distance between the plates, d = 6 cm = 0.06 m

The electric field between the plates is given by

E = V / d

E = 60 / 0.06 = 1000 N/C

Thus, the electric filed between the plates is 1000 N/C.

A construction worker pushes a wheelbarrow with a total mass of 50.0 kg. What is the acceleration of the wheelbarrow if the net
Vaselesa [24]

Answer:

1.5m/s²

Explanation:

Given parameters:

Mass of the wheelbarrow = 50kg

Net force applied  = 75N

Unknown:

Acceleration of the barrow = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

 Now insert the parameters and find the acceleration

       75  = 50 x acceleration

      Acceleration  = 1.5m/s²

True or false <br> Impulse is defined as the force exerted on an object times the time it lasts.
Sati [7]

Answer: true

Explanation:   when two objects collide and completely bounce apart with no lasting deformation or generation of heat, the collision is said to be elastic.
