Answer:

2156J

Explanation:

Given parameters:

Height of lift  = 10m

Mass  = 22kg

Unknown:

Work done by the machine  = ?

Solution:

Work done is the force applied to move a body through a certain distance.

So;

        Work done  = Force x distance

Here;

       Work done  = mass x acceleration due to gravity x height

      Work done  = 22 x 9.8 x 10  = 2156J

Answer:

They will never meet.

Explanation:

Given that three sharks are located at the vertices of an equilateral triangle whose side equals LL. They all start moving simultaneously with a constant speed vv, with the first shark heading constantly toward the second, the second toward the third, and the third toward the first. How soon will the sharks converge at one point ?

Since the three sharks are located at the vertices of an equilateral triangle whose side equals, and the first shark is moving toward the second, the second is moving toward the third, and the third shark is moving toward the first, the movement of the three shark will form a circular motion.

Since the three sharks are moving at a constant speed, the three sharks will never meet because the distances between them are also the same.

The three sharks will therefore continue to move till infinity.

Given parameters:

Number of rotations  = 50times

Time taken  = 2.5s

Unknown:

Period  = ?

Solution:

The period is the time taken for a body to make one complete rotation. It is mathematically expressed as;

     Period  = [tex]\frac{time taken}{number of rotation}[/tex]  

    Period = [tex]\frac{2.5}{50}[/tex]    = 0.05s

Answer:

Explanation:

Using the below formula

Speed of sound = ( distance between observers) *2/(total time taken)

Now putt the given values ,

time taken = 0.80 sec

distance = 256 m

hence

V of sound= 256*2/0.80

V of sound = 640 m/sec

Answer:

the initial velocity is 20 m/s   and  the acceleration is 2 m/s²

Explanation:

Given equation of motion, v = 20 + 2t

If V represents the final velocity of the object, then the initial velocity and acceleration of the object is calculated as follows;

From first kinematic equation;

v = u + at

where;

v is the final velocity

u is the initial velocity

a is the acceleration

t is time of motion

If we compare  (v = u + at)   to     (v = 20 + 2t)

then, u = 20    and  

         a = 2

Therefore, the initial velocity is 20 m/s   and  the acceleration is 2 m/s²

Normal ocean waves are caused by the wind, weather, tides, and currents, whereas tsunamis are powered by a geological force. Tsunami waves are surface gravity waves that are formed as the displaced water mass moves under the influence of gravity and radiates across the ocean like ripples on a pond.

The motion of a car and the wheel is kinda interesting, actually. If the wheel is turned right, the wheels will turn right. If it's left, the wheels will go left, you get the idea. The car will move that direction if it's in motion, though.

Answer:

In space, rockets zoom around with no air to push against. ... Rockets and engines in space behave according to Isaac Newton's third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.

Explanation:

:)

A balanced force is required for a change in the direction of the motion.

According to Newton's second law of motion, the force applied to a body is directly proportional to the product of mass and acceleration of the body.

Balanced forces are those that are opposite in direction and equal in size. When forces are balanced there is no change in direction.

Thus, when there is change in direction, a balance force can be applied to cancel the change in direction of motion.

Answer:

161.7N

Explanation:

Given parameters:

Mass of the box  = 55kg

Coefficient of friction  = 0.3

Applied force  = 140N

Unknown:

Frictional force on the box = ?

Solution:

The frictional force on the box is a force that opposes the motion of the box.

To find the value of this force;

        Fr  = u m g

u is the coefficient of static friction

m is the mass

g is the acceleration due to gravity

 So;

     Fr  = 0.3 x 55 x 9.8  = 161.7N

Answer:

D

Explanation:

Increasing temperature or pressure some times make the condition favorable to the reaction. Similarly increasing surface area  of reacting mixture also helps to increase the reaction rate.

The rate of  a reaction is the rate of decrease in concentration of reactant or the rate of increase in concentration of the products. The rate of a reaction depends on several factors such as temperature, pressure, surface area etc.

Fir an endothermic reaction, as the temperature increases, reaction rate increases. Similarly, as the pressure increases, the reaction in which the number of moles of gaseous reactants is higher than that in products, rate increases.

The concentration of reactants must be sufficient for the reaction and decreasing the concentration of reactants does not favor an increase in reaction rate. Hence, option D is correct.

Answer:

X = 2146.05 m

Explanation:

We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.

We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:

X = Vt   (1)

However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:

t = √2h/g   (2)

Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:

t = √(2*2500)/9.8

t = 22.59 s

Now replacing into (1) we have:

X = 95 * 22.59

This is the distance where the package should be released.
