How you can prevent thermal energy from moving by conduction, convection, and radiation?
Vanyuwa [196]

Answer:

Using insulating materials is the best way to prevent heat transfer by conduction and convection. Insulating materials are poor conductors of thermal energy and also limit the movement of air in spaces, reducing convection. Insulation slows the rate at which unwanted energy enters the home in the summer.

Explanation:

Easy peasy.

Cart A is pulled with a 2 Newton force for 2
nata0808 [166]

The cart A experienced the greatest impulse.

The given parameters;

  • force exerted on Cart A = 2 N
  • time of force action on cart A = 2 s
  • force exerted on cart B = 1
  • time of force action on cart B = 3 s

Impulse is defined as the product of the applied force  and time of action of the applied force.

J = Ft

where;

J is the impulse

F is the applied force

t is the time of action

The impulse experienced by cart A;

J = 2 x 2 = 4 Ns

The impulse experienced by cart B;

J = 1 x 3 = 3 Ns

Thus, the cart A experienced the greatest impulse.

Two charges that are separated by one meter exert 1-N forces on each other. If the charges are pushed together so the separation
Nana76 [90]

Answer: 16N

Explanation:

According to coulombs law which states that the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically,

F = kq1q2/r²

If two charges that are separated by one meter exert 1-N forces on each other, the equation will become

1 = kq1q2/1²

kq1q2 = 1 ... (1)

If the charges are pushed together so the separation is 25 centimeters, the force between them becomes,

F = kq1q2/0.25² (25cm converted to meters)

0.0625F = kq1q2 ... (2)

Dividing equation 1 by 2 to determine the force F on each charges, it becomes;

1/0.0625F = kq1q2/kq1q2

1/0.0625F = 1

0.0625F = 1

F = 1/0.0625

F= 16N
