Answer:

b) origin

Explanation:

Motion is when a body changes position in space with respect to time. There are four types of motion namely

1. circular motion: this is the motion of an object along a circular path eg. the motion of a  car tyre.

2. random motion: it is the motion of a body in zigzag manner e.g the motion of smoke from the exhaust pipe of a vehicle as it rises into the atmosphere

3. oscillatory : also known as the to and fro movement of a body e.g a pendulum swing

4. Linear motion: The motion of a body on a straight line. also known as translational motion e.g the motion of a car

Parameters/ terminologies used in motion are

velocity

displacement

distance

acceleration,

time,

speed

Motion in space and time starts from a point known as Origin

Maxwell’s theory of Electromagnetism in 1865 was the first "unified field theory" _________ no further theory has united the ele
Andrei [34K]

Answer: E.  and Electroweak in 1961 the only other, as

Explanation:

This is more an English grammar question than a physics question, so taking that perspective, one should look for the answer that best completes the sentence.

Based on the word "first" in the sentence, implying the need for a conjunction to join the two theories and the last part of the sentence does not give a reason but further supports the determination of the theory being the first unified theory.

So, to complete the sentence, the best option is;

Maxwell’s theory of Electromagnetism in 1865 was the first "unified field theory" and Electroweak in 1961 the only other, as no further theory has united the electroweak field with either the Strong (Hadronic) force or Gravity.

You punt a ball straight up at 20 m/s. What is the balls hangtime
Natalija [7]

The hang time of the ball is 4.08 s

Explanation:

The ball is in free fall motion: this means that it is acted upon gravity only, so its acceleration is the acceleration of gravity,

a=g=-9.8 m/s^2

downward (the negative sign refers to the downward direction).

Since this is a uniformly accelerated motion, we can solve the problem by using the following suvat equation:

v=u+at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

First we calculate the time it takes for the ball to reach the maximum height, where the velocity is zero:

v = 0

Substituting:

u = +20 m/s

a=-9.8 m/s^2

we find t

t=\frac{v-u}{a}=\frac{0-20}{-9.8}=2.04 s

The motion of the ball is symmetrical, so the total time of flight is just twice the time needed to reach the maximum height, therefore:

T=2t=2(2.04)=4.08 s
