Answer:

A)   Wn = 90J

B)   W1 = 100J

     W2 = 10J

Explanation:

A) The net work done on the box is calculated by using the following formula:

W_n=(F_1-F_2)d     (1)

F1 = 100N

F2 = 10N

d: distance on which the box is moved = 1m

You replace the values of the parameters in the equation (1):

W_n=(100N-10N)(1m)=90J

The net work on the box is 90J

B) The total work done by each force is:

W_1=F_1d=(100N)(1m)=100J\\\\W_2=F_2d=(10N)(1m)=10J

The first box does a work of 100J and the second force does a force of 10J

A mass oscillates up and down on a vertical spring with an amplitude of 3 cm and a period of 2 s. What total distance does the m
harina [27]

Explanation:

It is given that,

A mass oscillates up and down on a vertical spring with an amplitude of 3 cm and a period of 2 s. It is a case of simple harmonic motion. If the amplitude of a wave is T seconds, then the distance cover by that object is 4 times the amplitude.

In 2 seconds, distance covered by the mass is 12 cm.

In 1 seconds, distance covered by the mass is 6 cm

So, in 16 seconds, distance covered by the mass is 96 cm

So, the distance covered by the mass in 16 seconds is 96 cm. Hence, this is the required solution.

Radiation transfers thermal energy through_________. Which accurately complete the statement waves direct contact of particles i
evablogger [386]

Answer:

waves

Explanation:

There are three major ways in which heat or thermal energy is transferred namely: conduction, convection and radiation. Please find the description of each below;

- Conduction is the method of heat transfer which involves a physical contact between the substances involved.

- Convection, on the contrary, occurs via a liquid medium

- RADIATION is a method of heat transfer which involves neither physical contact or liquid medium (matter) but occurs through WAVES e.g electromagnetic waves. For example, the sun transfers heat to the Earth via RADIATION.
