A positively charged particle initially at rest on the ground accelerates upward to 160 m/s in 2.90 s . The particle has a charg
Ksju [112]

Answer:

E = 5.5 10² N /C

Explanation:

For this exercise let's use Newton's second law

         F = m a

the force is electric

        F = q E

we substitute

        q E = m a

         E = \frac{m}{q} \ a               (1)

the acceleration can be found with kinematics,

        v = v₀ + a t

as the particle starts from rest v₀ = 0

        a = v / t

        a = 160 / 2.90

        a = 55.17 m / s²

 

the relationship

        q / m = 0.100 C / kg

        m / q = 10 kg / C

we use equation 1

        E = 10  55.17

        E = 551.7 N / C

        E = 5.517 10² N / C

ask for the result with two significant figures

         E = 5.5 10² N /C

A battery of 1 V gives how much energy to each Coulomb of charge? A. Not enough info B. 5 Joules C. 1 Joule D. 0.5 Joules
Artist 52 [7]

C. 1 Joule

Explanation:

Given:

Voltage = 1V

Quantity of charge = 1coulomb

Unknown:

Energy = ?

Solution:

The amount of work done is often related to the energy in a system.

In this electrical circuit, work done is the voltage that moves a particular charge.

    work done = q x v

  q is the quantity of charge

  v is the voltage

the potential difference in circuit is the driving force of charges.

 Work done = energy = qv

inputting the parameters;

   Work done =  1 x 1 = 1J

What problems would we have if Pascal had failed to give the Pascal's law? Write some points.
Reika [66]
Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.

What is the value of acceleration due to gravity at heght h=4re​
Norma-Jean [14]

Answer: Formula for Acceleration Due to Gravity

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.please mark as brainliest
