What is the total moved without regard to direction​
soldi70 [24.7K]

The entire motion of an object, regardless of direction.

In physics, motion is that the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of regard to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without regard to their cause is called kinematics, while the branch studying forces and their effect on motion are named dynamics.

If an object isn't changing relative to a given frame of reference,  the thing is said to be at rest, motionless, immobile, stationary, or to possess a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as  there's no absolute frame of reference, Newton's concept of absolute motion can't be  determined

A positively charged particle initially at rest on the ground accelerates upward to 160 m/s in 2.10 s. The particle has a charge
mamaluj [8]

Answer:

The magnitude of the electric field is 8.6\times10^{2}\ N/C

Explanation:

Given that,

Time t = 2.10 s

Speed = 160 m/s

Specific charge =Ratio of charge to mass = 0.100 C/kg

We need to calculate the acceleration

Using equation of motion

a=\dfrac{v-u}{t}

Put the value into the formula

a=\dfrac{160-0}{2.10}

a=76.19\ m/s^2

We need to calculate the magnitude of the electric field

Using formula of electric field

E=\dfrac{F}{q}

E=\dfrac{ma}{q}

E=\dfrac{a+g}{\dfrac{q}{m}}

Put the value into the formula

E=\dfrac{76.19+9.8}{0.100}

E=8.6\times10^{2}\ N/C

The direction is upward.

Hence, The magnitude of the electric field is 8.6\times10^{2}\ N/C

a farmer lifts a bale of hay that is 12m off the ground . If he uses a force of 350 n, how much work does the farmer do?
hjlf

Answer:

4200 Joules

Explanation:

Work done =force x distance

From the question , we’re given f =350N ,

d = 12m

Using the above formula, we have

Workdone = 350 x 12

= 4200 Joules
