Answer:

0.024m^3

Explanation:

=======

Answer:

=======

Given:-

Mass of the block of wood = 24 kg

Volume of wood = 0.032 m^3

Density of water = 1000kg/m^3

Now,

Density of wood is given by,

\frac{m}{v} = \frac{24}{0.032} \\

\frac{m}{v} = 750 \: kg/m ^{3}

Therefore,

The density of wood is 750kg/m^3

By principle of floatation,

Mass \:of\: wood = Mass\: of\: liquid \:displaced

Therefore,

Mass of liquid displaced = 24kg

Volume of liquid displaced (v),

\frac{m}{v} = \frac{24}{1000} \\

\frac{m}{v} = 0.24m ^{3}

Now,

Since the volume of the wood is equal to the volume of water displaced, it is 0.024m^3

=====

Note:

=====

=> The volume of the wood below the water surface is the volume of water displaced.

=> Buoyant\: force = Weight\: of\: the \:displaced\: water.

According to the statement, on the ball thrown upward from the ground, it will reach the ground at time t=12 seconds.

The ball will reach the ground at time t when its vertical displacement is zero. We can use the equation for vertical displacement, \(y = v0t - (1/2)gt^2\), where v0 is the initial velocity, g is the acceleration due to gravity, and t is the time. Plugging in the given values, we get:

\(0 = 60t - (1/2)(10)t^2\)

Rearranging the equation and factoring out t, we get:

t(60 – 5t) = 0

This gives us two possible values for t: 0 and 12 seconds. Since the ball is thrown at t=0, the time when it reaches the ground is t=12 seconds.

The pressure over the diver at a depth of 10 m in the ocean is 100,450 Pa. It is important to note that this pressure is in addition to the atmospheric pressure and may have adverse effects on the diver if not managed properly.

The pressure over the diver at a depth of 10 m in the ocean can be calculated using the formula: pressure = density x gravity x depth. Here, the density of the seawater is given as 1025 kg/m3 and the depth of the diver is 10 m. The acceleration due to gravity is 9.8 m/s2.
So, pressure = 1025 x 9.8 x 10 = 100,450 Pa.
Scuba divers use specialized equipment like pressure gauges and dive computers to monitor and control their exposure to pressure underwater.

The tension in the towline of a motorboat being towed at a constant speed which yields a value of 2,138.46 N.

To find the tension in the towline when the motorboat is moving at 13.0 m/s,

we can use the formula for power:

Power = Force x Velocity.
Where,

the power delivered by the engine to the propeller is 27.8 kW,

which we need to convert to Watts: 27.8 kW * 1000 = 27800 W.

The velocity of the motorboat is given as 13.0 m/s.
Rearranging the formula to find the force (tension in the towline),

we get: Force = Power / Velocity.
Substituting the values, we get,
Force = 27800 W / 13.0 m/s.
Force = 2,138.46 N.

Therefore, the tension in the towline when the motorboat is moving at 13.0 m/s would be approximately 2,138.46 Newtons.

Explanation:

Complete Question:

A force of 5.0 N moves a 6.0 kg object along a rough floor at a constant speed of 2.5 m/s.

(a) How much work is done in 25 s?

(b) What power is being used?

(c) What force of friction is acting on the object?

Answer:

a. Workdone = 312.5 Joules.

b. Power = 12.5 Watts.

c. Force of friction = 5 Newton.

Explanation:

Given the following data;

Force = 5N

Speed = 2.5m/s

Mass = 6kg

Time = 25 secs

a. To find the work done.

We would first solve for the distance covered by the object.

Distance = speed * time

Distance = 2.5 * 25

Distance = 62.5 meters.

Workdone = force * distance

Workdone = 5 * 62.5

Workdone = 312.5 Joules.

b. To find the amount of power being used.

Power = workdone/time

Power = 312.5/25

Power = 12.5 Watts.

c. To find the force of friction is acting on the object.

Since we know that there is no net force acting on the body. Therefore, the force of friction is equal to 5 Newton.

a) Power is being used will be 12.5 Watts.

b)  Force of friction is acting on the object will be 5 Newton.

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).

Mathematically it is defined as the product of the coefficient of friction and normal reaction.

The given data in the problem is;

m is the mass of object =6.0 kg

u is the speed =2.5 m/s

a) Power is being used will be 12.5 Watts.

The distance traveled by the object is;

\(\rm d = v \times t \\\\ \rm d = 2.5 \times 25 \\\\ \rm d = 62.5 m\)

The work done is the product of force and displacement;

\(\rm W = F \times d \\\\ \rm W = 5 \times 62.5 \\\\ \rm W = 312.5 \ J\)

The power is the ratio of work done to the  time;

\(\rm P= \frac{W}{t} \\\\ \rm P= \frac{312.5 }{25 } \\\\\ \rm P=12.5 \ Watt\)

Hence Power is being used will be 12.5 Watts.

b) Force of friction is acting on the object will be 5 Newton.

If the all unbalanced force is zero the net force is equal to the force of friction;

The force of friction= Net force

Force of friction= 5 Newton.

Hence the force of friction is acting on the object will be 5 Newton.

When the crest of one wave passes through the trough of another wave, destructive interference takes place.

The crest and trough of a wave, respectively, are its highest and lowest surface portions. The wave height is the vertical distance between the peak and trough. The wavelength is the horizontal separation between two consecutive crests or troughs.

When the crest of one wave passes through the trough of another wave, interference takes place.

This interference can be constructive, where the amplitudes of the waves add up, resulting in a larger wave, or destructive, where the amplitudes of the waves cancel out, resulting in a smaller wave or no wave at all.

The type of interference that occurs depends on the relative amplitudes, wavelengths, and phases of the two waves.

The ocean conveyor belt is a global system of deep and surface ocean currents that circulate water around the world. It is driven by differences in water density, temperatures, and salinity.

Salinity is the measure of the amount of dissolved salts in a given volume of water. It is typically expressed as parts per thousand (ppt) or parts per million (ppm). Salinity can be found in most bodies of water, including oceans, rivers, and lakes. Salinity levels can vary greatly depending on the source of the water, the amount of rainfall, and other factors. In general, the higher the salinity, the more difficult it is for organisms to survive in the water. High salinity levels can also affect the taste and smell of the water, and can be an indicator of water pollution. Salinity can also be an important factor for many human activities, such as agriculture, industry, and navigation.

The ocean conveyor belt has a huge effect on coastal climates by transporting heat from the tropics to higher latitudes, where it is released into the atmosphere. This helps warm coastal climates, resulting in milder winters and cooler summers. It also helps to reduce the effects of extreme weather events such as droughts and floods, by moderating temperatures and redistributing moisture.
