Newton's second and third law can be found the correct answer is:
Pressure is defined by the relationship between forces and area,
P = F / A
Where P is pressure, F is force and A is area
F = P A
Newton's second law is that the sum of the external forces of a body is proportional to the mass of the body and the acceleration
Newton's third law or action and reaction says that forces in nature appear in pairs on the two interacting bodies, the magnitude of the force is equal, but in the opposite direction; each one is applied to one of the bodies.
A free-body diagram of the process is shown in the attachment
B + F - W = m a
W = m g
Where B is the thrust, F the force of air exit, W the weight, m the mass and the acceleration of the body
Archimedes' principle states that the vertical thrust on a body is equal to the fart of the dislodged fluid, in this case air.
B =ρ_{air} g V_{air}
Where ρ and V_ {air} are the density and volume of the air, respectively,
It's substitute
ρ_{air} g V_{air} + P A - m g = m a
a =
The mass of the body is formed by the mass of the balloon plus the mass of air that it contains
Let's analyze this expression in three moments
In conclusion with Newton's second and third law we find the correct answer is:

Answer:
Check the explanation
Explanation:
From given data, it can be noted that 95% of given confidently data, means 5% of data is uncertain. According to the question, we have to calculate uncertainty in Cp .
Kindly check the attached image below for the step by step explanation to the question above.
Answer:
Surface tension in water
Friction between tires and pavement
Dissolution of salt in water
Explanation:
Surface tension in water: It is due to the electrostatic force of attraction (cohesive force) between water molecules.
Friction between tires and pavement: It is due to the attractive force between tires and pavement.
Dissolution of salt in water: The ions of and
separate due to the strong attraction of water molecules.
The image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.
<h3>What is Geometry?</h3>It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Triangle XYZ has vertices X(0, 2), Y(4, 4), and Z(3, –1).
If the triangle is ΔXYZ. Then the image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.

Answer:
Explanation:
Given
Wavelength of light
Screen is away
Distance between two adjacent bright fringe is
When same experiment done in water, wavelength reduce to
So, the distance between the two adjacent bright fringe is
Keeping other factor same, distance becomes
