Answer:
Pressure is a quantity that may be measured in a variety of units such as atm and bar. However, the Pascal is used to measure pressure in the SI system. One Pascal is the pressure exerted perpendicularly on an area of one square meter by a force of magnitude one Newton.
The three kinematic equations provided by Newton explain or determine the acceleration of the stone after it departs the ramp.
<h3>What is acceleration?</h3>
The rate of velocity change concerning time is known as acceleration.
There are three kinematic equations used to find the acceleration depending upon the perameters;
1.
2.
3.
The acceleration of the marble after it leaves the ramp is described or found by the three kinematic equations given by Newton.
Hence there are three kinematic equations to support your discussion.

Answer:
m₁ = 4.65 Kg
m₂ = 1.15 Kg
Explanation:
given,
heavier mass be equal to m₁
lighter mass be equal to m₂
distance between the two objects = 20.5 cm = 0.205 m
force of attraction = 8.50 x 10⁻⁹ N
combine value of mass = 5.80
m₁ + m₂ = 5.80 Kg
using formula
on solving the above equation
m₁ = 4.65 Kg
now,
m₂ = 5.80 - 4.65
m₂ = 1.15 Kg
With the input of 68 J of energy, the temperature rises by 13 K, and the molar heat capacity of gallium is 25.86 J/(mol*K)
68 J * 25.86 J/(mol·K) * x mol=13 K
x=13/(68*25.86)=0.00739 mol
Molar mass of gallium is 69.723 g/mol, making the mass of this sample 0.515 g of gallium:
0.151 g = 68.723 g/mol * 0.00739 mol
The density of gallium is 5.91 g/cm^3, making the volume of this sample
0.872 cm^3 of gallium:
0.872 cm^3 = (0.515 g) / (5.91 g/cm^3)
The torque produced on an electric dipole by an electric field is defined as
where:
- p: the dipole moment in (c.m)
- E: electric field in (N/c)
Thus
<em>note that the unit of the torque is N.m</em>
