Clarisse had three substances. A white substance was waxy and malleable. A red crystal was translucent, and it cracked when she hit it with a hammer. A silver substance could be flatten by hitting it with a hammer, but it did not crack. Which two statements could be true?

Answer:

The time taken for the ball to get to the batter is 0.41 s.

Explanation:

Given;

initial velocity of the baseball, u = 45 m/s

horizontal distance between the pitcher and the batter, X = 18.39 m

The horizontal distance or range of a projectile is given as;

X = ut

where;

t is the time of flight

u is the initial velocity

t = X / u

t = 18.39 / 45

t = 0.41 s

Therefore, the time taken for the ball to get to the batter is 0.41 s.

Uniform circular motion is defined as the constant-speed movement of an object in a circle.

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:

Pressure = 100 Pascals

Explanation:

[tex]pressure = \frac{force}{area} \\ = \frac{150 \times 10}{15} \\ = \frac{1500}{15} \\ = 100 pa[/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:

force is a force between two surfaces that are sibling

1. it acts parrell

2. it is caused due to intermolecular interactions between two bodies

Answer:

Yes the student is correct

Explanation:

The first law of thermodynamics states that energy can neither be created nor destroyed

The second law of thermodynamics states that the entropy (disorderliness) of an isolated system always increases

Therefore, whereby energy is not supplied to maintain the orderly oscillatory motion with constant amplitude, the amplitude of the system is bound to reduce with time that is the vibration of the system must be damped

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:

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.

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

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°

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:
