Newton’s first Law is law of inertia or resistance to change of motion. Objects in motion tend to stay in motion or an object at rest tends to stay at rest, unless acted on by an outside force.
Newton’s second Law is F=ma is equal to the rate of change of momentum with respect to time dp/dt. This means force is equal to mass times acceleration or F= mass*(d^2x/dt^2)
Newton’s third Law is for every force there is an equal and opposite force. Meaning if I push on the ground, the ground pushes back on me equally an opposite.
Hope this helps you understand Newton’s three laws of motion. Any questions please ask!!
Thank you!!
Answer: 1.04N
Explanation:
Given
q1 = 2*10^-6C
q2 = 3.6*10^-6C
r = 0.25m
k = 9*10^9
Magnitude of electrostatic force can be calculated by using coulomb's law. Coulomb's law states that, "the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them."
F =(kq1q2) / r²
F = (9*10^9 * 2*10^-6 * 3.6*10^-6) / 0.25²
F = 0.0648/0.0625
F = 1.04N
The type of electrostatic force between the charges is the repulsive force

where T=temperature
For T = 387K
For T = 774
dividing eqn 1 and eqn 2
Thus,the ratio is
Answer:
A
Explanation:
Can read mass precisely, commonly reading error of +0.05g
The heat capacity is given by the expression:
When the is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in , we can then determine the specific heat "C" by simply remplazing in the expression.
