What is the equivalent resistance between points a and b in the figure?

How do scientist know that seismic waves can be either compressional or transverse

nasty-shy [4]

Hey there!

<span>Scientists know that seismic waves can be either compressional or transverse because there are horizontal and vertical movements during an earthquake. Horizontal movements are compressional while vertical movements are transverse.

Thank you!</span>

An object is attached to a vertical spring and bobs up and down between points A and B. Where is the object located when its kin

gtnhenbr [62]

Answer:

a. at either A or B

Explanation:

Kinetic energy may be defined as the energy of the system or an object which is due to its velocity of the object it possess.

In the context, an object having mass is attached to spring which is vertical and the object moves up and down due to spring effect between points A and B. Now these points A and B are the extreme points after which the object bounces back.

At point A and B, the velocity of the object becomes zero and hence the kinetic energy of a body varies directly proportional to its velocity.

i.e. Kinetic energy $= \frac{1}{2} \text{mass} \times (\text{ velocity})^2$

Explain how heat transfer is occurring through convection, radiation AND conduction in this picture.

frosja888 [35]

A cup of tea/coffee transfers heat via conduction, convection and radiation.

Conduction:

Heat transfer from a coffee to the spoon is in direct contact
Inner part of the tea cup against hot liquid will transfer heat to the outer part and saucer.

Convection:

Movement of molecules within the coffee. Hot molecules of the tea at the middle of the drink will be eventually make their way to the outer part of the drink near the tea cup, where they will loose their heat.

Radiation:

Thermal radiation is the loss of heat from a solid object in to atmosphere via the release of electromagnetic radiation. So hot outer edge of the teacup loss the energy to its surroundings via thermal radiation.

A stockroom worker pushes a box with mass 11.2 kg on a horizontal surface with constant speed of 3.50m/s. The coefficient of kin

stellarik [79]

Answer:

3.125 m

Explanation:

We are given that

Mass of box=m=11.2 kg

Speed of box=u=3.5m/s

Coefficient of kinetic friction= $\mu_k=0.2$
