Explanation:

Pressure due to the weight of a liquid of constant density is given by p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity

What force is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s²?

mihalych1998 [28]

Newton's Second law of motion:

Force = (mass) x (acceleration)

Force = (15kg) x (8m/s²) = 120 kg-m/s² = 120 newtons

A planar electromagnetic wave is propagating in the +x direction. At a certain point P and at a given instant, the electric fiel

Free_Kalibri [48]

Answer:

$B=2.74\times 10^{-10}\ T$

Explanation:

It is given that,

A planar electromagnetic wave is propagating in the +x direction.The electric field at a certain point is, E = 0.082 V/m

We need to find the magnetic vector of the wave at the point P at that instant.

The relation between electric field and magnetic field is given by :

$c=\dfrac{E}{B}$

c is speed of light

B is magnetic field

$B=\dfrac{E}{c}\\\\B=\dfrac{0.082}{3\times 10^8}\\\\B=2.74\times 10^{-10}\ T$

So, the magnetic vector at point P at that instant is $2.74\times 10^{-10}\ T$ .

A well-insulated cup of water is too hot to make tea, so you mixed it with an equal amount of cool water to lower the temperatur

KonstantinChe [14]

Answer:The change in entropy of the total amount of water is negative as a result of the mixing.

Explanation:If you increase temperature, you increase entropy

Also More energy gives you greater entropy and randomness of the atoms.

Find the change in velocity of a 369 g hockey puck subject to the force shown below.

Elena-2011 [213]

Answer:

The change in velocity is 15.83 [m/s]

Explanation:

Using the Newton's second law we have:

ΣF = m*a

The force in the graph is 185 N, therefore:

$185=0.369*a\\Where\\a=acceleration made it by the force [m/s^2]$

$a=501.35[m/s^2]$

Now using the following kinematic equation:

$V^{2}=Vi^{2} + 2*a*(x-xi) \\where\\V=final velocity [m/s]\\Vi= initial velocity [m/s] = 0 the hockey disk is in rest when receives the hit.\\ x = Final position [m] = 0.4 m\\xi = initial position [m] = 0.15m\\$

Now replacing the values:

$V^{2}=0 + 2*501.35*(0.4-0.15)\\ \\V= 15.83[m/s]$
