What is the difference in forces and displacement when comparing positive and negative work?

Physics

8_murik_8 [283]3 years ago
7 0

Answer:

Explanation:

Work is the product of force and displacement.  Work is positive if force and displacement moves in the same direction. Work is negative if force and displacement moves in opposite direction.  Take for example, a load is to move from point A to point B in the forward direction. if you apply force on the load from point A to B work done on the load is positive. If it happens that the force you apply is to the opposite direction, the work done will be negative.

The acceleration produced by a net force on a body is inversely proportional to the mass of the body. true or false
ExtremeBDS [4]
Hi! This is true because F = mA. If we increase mass, we should expect acceleration to be lower. If we decrease mass, we should expect acceleration to increase. Think of it this way - it is harder to make a heavier person go faster then slower and faster again.

The amplitude of an electric field is 0.4 v/m 23 km from a radio transmitter. What is the total power emitted by the transmitter
ycow [4]

To solve this problem we will apply the concepts related to the relationship between the voltage, the electric field and the distance, once the voltage is found we will use the definition of power, which is defined as the square of the voltage over the resistance. This is,

V=Ed

E = Electric field

d= Distance between the points

Replacing,

V=0.4*23000

V=9200 V

Now applying the relation for power we have,

P=\frac{V^2}{R}

Here

V = Voltage

R = Resistance

Replacing,

P= \frac{9200^2}{377}

P=224509.3 W

Therefore the total power emmited by the transmitter is 224509.3 W
