<u>Given data:</u>

mass of oil  = 2 × 10¹⁴ kg,

charge (q)   = 8 × 10⁻¹⁸ C

drop is stationery between two parallel plates

and plates are at a distance of (d) = 20 mm

                                                        = 0.020 m,

Calculate potential difference (V) = ?

We know that the potential difference

                                  V = E.d Volts

                        Where

                                   d = distance between plates in meters

                                    E = electric field in N/C

                                      = m.g/q

                                    q = charge in coulombs

                                    m = mass in kg

Lets find out  

<em>                         E = m.g/q</em>  N/C

                           = (2 × 10¹⁴ × 9.8)/ 8×10⁻¹⁸    N/C

                           =  2.45 ×10³² N/C

 Now calculating V = E.d

                                 = 2.45 ×10³² × 0.020

                                 = 4.9  ×10³⁰ volts

<em>The potential difference is 4.9  ×10³⁰ volts</em>

Write the equations of motions​
Sav [38]

Answer:

In physics, equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.[1] More specifically, the equations of motion describe the behaviour of a physical system as a set of mathematical functions in terms of dynamic variables. These variables are usually spatial coordinates and time, but may include momentum components. The most general choice are generalized coordinates which can be any convenient variables characteristic of the physical system.[2] The functions are defined in a Euclidean space in classical mechanics, but are replaced by curved spaces in relativity. If the dynamics of a system is known, the equations are the solutions for the differential equations describing the motion of the dynamics.

The 0.15kg baseball has a speed of v=30 m/s just before it is struck by the bat. It then travels along the trajectory shown befo
notka56 [123]

The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N

The mass of the baseball, m = 0.15 kg

The speed at which it moves, v = 30 m/s

Time at which the baseball was in contact with the bat, t = 0.75 ms

t = 0.75/1000 s

t  = 0.00075 s

The impulsive force is given by the formula:

F=\frac{mv}{t}

Substitute m = 0.15 kg, v = 30, and t = 0.00075s into the formula above:

F=\frac{0.15 \times 30}{0.00075} \\\\F=6000N

The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N
