1. Cannonball fired upward from a cannon

here in this cannon we can say kinetic energy is converted into potential energy of the cannon.

here this is because when cannon ball is shot with some speed its kinetic energy is converted into potential energy at the top point of its path

2. Diver jumping from a spring board

when diver is jumping on spring board then spring potential energy is converted into kinetic energy of the diver.

here when spring is compressed the energy in it is in the form of spring potential energy while at the other form it is converted into kinetic energy of the diver when he jump off.

3. Squirrel jumping from a tree and landing on the net of a trampoline.

When squirrel is jumping from tree and landing on the net trampoline the gravitational potential energy of the squirrel will transform into the kinetic energy of squirrel and then it is transformed into the potential energy of the net trampoline.

How does population stimulate social change?
Dmitry_Shevchenko [17]

Answer:

A change in the size of the population may bring about changes in the culture. For example, food brought to this country by immigrant groups have become common in many American kitchens. Population increases and decreases affect the economy. For example, by increasing the demand for goods and services, a growing population may increase employment and stimulate the economy. An increase in the general population also means that there are more people occupying the same amount of space, which creates more crowded conditions. In addition, the larger population brings increased demand for energy, food, housing, schools, stores, and transportation. People also bring about changes simply by moving from one place to another. Migrations of people within a country can cause social changes, such as the loss of regional distinction within the country. Social and cultural changes also result from changes in the average age of a population. When fewer people are having babies, for example, there is less need for schools, recreation centers, and other services geared toward children.

Car enthusiasts often lower their cars closer to the ground as a matter of style. James wants to lower his car by replacing all
Alexandra [31]

Answer:

\Delta h=0.0364\ m=3.64\ cm

Explanation:

Given:

  • change in stiffness constant of the spring on replacing the original springs, \delta k=5355\ N.m^{-1}
  • mass of the car, m=1455\ kg
  • initial length of the original car-spring before compression, l_i=12\ cm=0.12\ m
  • final length of the original car-spring after compression, l_f=8.55\ cm=0.0855\ m

So, weight of the car:

w=m.g

w=1455\times 9.81

w=14273.55\ N

<u>Now the spring constant of original spring:</u>

w=4k_o.(l_i-l_f) (since 4 springs are in parallel)

14273.55=4k_o\times (0.12-0.0855)

k_o=103431.522\ N.m^{-1}

<u>So the stiffness constant of the new springs:</u>

k_n=k_o-\delta k

k_n=103431.522-5355

k_n=98076.522\ N.m^{-1}

<u>Now the height lowered:</u>

w=k_n.4\Delta h (since 4 springs are in parallel)

14273.55=4\times98076.522\times \Delta h

\Delta h=0.0364\ m=3.64\ cm

What is the current in the circuit at the instant the capacitor begins to charge (the instant the switch is first closed)?
daser333 [38]

Complete  Question

The  complete question is shown on the first uploaded image

Answer:

The current is  I  =  4.2 \ A

Explanation:

From the question we are told that

    The  voltage of battery is  V  = 25 V

     The  capacitance of capacitor is  C =  15 \mu F

      The resistance of the resistor is  R =  6 \Omega

Generally the current at the instant the capacitor starts charging is  

             I  =  \frac{V}{R}

substituting values

           I  =  \frac{25}{6}

         I  =  4.2 \ A

An 8.0 cm object is 40.0 cm from a concave mirror that has a focal length of 10.0 cm. Its image is 16.0 cm in front of the mirro
svet-max [94.6K]
 We can rearrange the mirror equation before plugging our values in. 
1/p = 1/f - 1/q. 
1/p = 1/10cm - 1/40cm
1/p = 4/40cm - 1/40cm = 3/40cm
40cm=3p  <-- cross multiplication
13.33cm = p

Now that we have the value of p, we can plug it into the magnification equation.

M=-16/13.33=1.2
1.2=h'/8cm
9.6=h'

So the height of the image produced by the mirror is 9.6cm.
