Answer:
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.
How to find pressure when mass and area is given?
Answer:
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second units are newtons per square meter, or N/m2.
Explanation:
Do you not feel the pressure when mass is on you?

Answer: m∠P ≈ 46,42°
because using the law of sines in ΔPQR
=> sin 75°/ 4 = sin P/3
so ur friend is wrong due to confusion between edges
+) we have: sin 75°/4 = sin P/3
=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16
=> m∠P ≈ 46,42°

A 5-N force is applied to a 3-kg ball to change its velocity from +9 m/s to +3 m/s. What is the impulse?
Answer:
-18 Nm
Explanation:
Impulse = Change of Momentum
I = ∆p
I = mv2 - mv1
I = 3 x 3 - 3 x 9
I = 9 - 27
I = -18 Nm

1.Explain how a beach ball and a bowling ball can be similar in sizebut differ in physical properties Be sure to discuss densitymass colorsize, and volume
2. How would each behave if you tossed them into air?
Answer:
well a beach ball could be any size at all a bowling ball is usually the same size the weight difference is inside of them inside the beach ball there's air although in a bowling ball there's cement or rock i don't know what they put inside the ball but anyway the bowling ball a lot higher density o it has more volume so the bowling ball is a lot heavier than just a beach ball
Explanation:
What causes earth's magnetic field to flip?
Answer:
The generation of Earth's magnetic field starts at its very center. Some researchers believe polarity reversals are caused by a disturbance in the balance between Earth's rotation and the temperature at the core, which alters the fluid motion of the liquid iron, but the exact process remains a mystery.
Which example demonstrates constant speed with changing direction?
Uniform circular motion is defined as the constant-speed movement of an object in a circle.
What is Speed?The definition of speed is. The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling.
Speed is classified as a scalar quantity because it has only one direction and no magnitude.
In summary, the act of turning away or in the opposite direction. reversal, reverse, reversion, turnabout, turnaround.

Answer:
The height of the hurdler when he clears the hurdle is approximately 1.1045 meters (high)
Explanation:
The given parameters are;
The distance the hurdler is from the hurdle, d = 0.535 m
The velocity with which the hurdler jumps, u = 6.82 m/s
The angle at which the hurdler jumps, θ = 67.9°
The horizontal component of the velocity is uₓ = u × cos(θ)
∴ uₓ = 6.82 × cos(67.9°) ≈ 2.566 m/s
The time it takes, t, the hurdler to get to the hurdle horizontally 0.535 m away is given as follows;
Time, t = Distance/Velocity = d/uₓ = 0.535 m/(2.566 m/s) ≈ 0.2085 s
t ≈ 0.2085 s
The kinematic equation of vertical motion, under gravity can be presented as follows;
h = [tex]u_y[/tex]·t - 1/2·g·t²
Where;
h = The height reached by the hurdler in time t
[tex]u_y[/tex] = The vertical component of the velocity = u × sin(θ)
g = The acceleration due to gravity
∴ [tex]u_y[/tex] = 6.82 m/s × sin(67.9°) ≈ 6.3189 m/s
[tex]u_y[/tex] ≈ 6.3189 m/s
Substituting the known values gives;
h = 6.3189 × 0.2085 - 1/2×9.8×0.2085² ≈ 1.1045 m
The height of the hurdler when he clears the hurdle, h ≈ 1.1045 m.

The rate of acceleration for a basketball that is falling to the ground is 9.8 meters per second. The force exerted on the basketball is 29.4 Newtons. What is the mass of the object?
A 1405 kg car is accelerating at
1.77 m/s? Its engine creates a forward
force of 3150 N, and air resistance
creates a backward force. What is
the magnitude (+) of the force of
air resistance or the car?
(Unit = N)
Answer:
fair = 663.15 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
∑F = forces applied [N]
m = mass = 1405 [kg]
a = acceleration = 1.77 [m/s²]
In this way, we have two forces, the one that develops the engine to move the car and the resistance force of the air that opposes the movement of the car.
[tex]3150-f_{air}=m*a\\3150-f_{air}=1405*1.77\\f_{air}=3150-2486.85\\f_{air}=663.15[N][/tex]

Answer: 1. It always acts in the direction opposite to the direction of motion. 2. It's magnitude is equal to that of the force trying to set the object in motion only until it starts to move.
Explanation: Properties of frictional forces:
1. Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies.
Explanation:
