A can opener makes work easier by increasing force.
Explanation
Technically a can opener is a simple lever that increases the force with which we remove the cap of the can. Levers are rod shaped objects with fulcrum at one end and the length of the lever has a positive impact on the force.
considering the equation
work=force*distance
indicates that increasing the length of the lever/can opener increases the work done by it.
Heat is transferred from the sun-warmed surface of the earth to the cooler overlying troposphere via <u>conduction.</u>

<h3>Heat transfer from earth to atmosphere:</h3>
Conduction, convection, latent heating, and water phase transitions all help to carry heat from the Earth's surface, which has been warmed by the Sun, to the cooler troposphere above.
Latent heat flux is the worldwide transfer of latent heat energy via water and air currents. Here, we demonstrate how air circulation transports latent heat energy horizontally to cooler regions, where it condenses into rain or is deposited as snow, releasing the heat energy that was previously trapped there.
When air is heated from below by sunshine or by coming into contact with a warmer land or sea surface, convection occurs and the air below becomes less dense than the air above.

Answer:
(a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
Explanation:
Given that,
Speed = 20 m/s
Angle = 40°
Height = 22 m
Time = 3.25 sec
(a). We need to calculate the distance
Using formula of distance
Put the value into the formula
(b). We need to calculate the horizontal velocity
Using formula of velocity
Put the value into the formula
We need to calculate the vertical velocity
Using equation of motion
Put the value into the formula
Negative sign shows the opposite direction.
We need to calculate the speed of ball
Using formula of speed
Hence, (a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
Answer:
