The angle of the free surface relative to the horizontal direction after deceleration is approximately 20.2 degrees.

Let's assume that the tank has a mass of m, the angle of the inclined surface is θ, and the height of the inclined surface is h. The initial kinetic energy of the tank is given by:

KE = (1/2)mv²

where v is the initial velocity of the tank. When the tank reaches the top of the inclined surface, its potential energy is given by:

PE = mgh

where g is the acceleration due to gravity (9.81 m/s²). Since there is no change in the total energy of the system (tank + water), we can equate the initial kinetic energy to the final potential energy:

(1/2)mv² = mgh

Solving for v, we get:

v = √(2gh)

When the tank decelerates with an acceleration of a, its velocity decreases at a rate of a m/s². The time taken for the tank to come to a complete stop is given by:

t = v/a

The distance traveled by the tank during this time is:

s = (1/2)at²

\(=\dfrac{1}{2} (\dfrac{v}{a})^2a = \dfrac{v^2}{2a}\)

The angle of the free surface relative to the horizontal direction after deceleration is given by:

\(\theta' = tan^{-1}\dfrac{s}{h}\)

Substituting the values of v and s, we get:

\(\theta' = tan^{-1}\dfrac{\sqrt{2gh}^2}{2ah}\\\\ = tan^{-1}\dfrac{2h}{3a}\)

Substituting the given values of h and a, we get:

\(\theta' = tan^{-1}\dfrac{2(9.81)sin(15)}{3.83}\\ = 20.2\)

Answer:I THINK it's 60km Because i pretty sure you multiply or divide it but, thats what i got.

Explanation:

30 x 20 = 60km

60 x 15 = 60km

anything times zero equals zero

division:

30 ÷ 15 = 02

The intensity of the circuit is 2 amps (option c).  (B) V =12 volts, R= 6 ohms.

To determine the intensity of the circuit, we can use Ohm's law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R).

Given:

Voltage (E) = 12 volts

Resistance (R) = 6 ohms

Applying Ohm's law, we can calculate the intensity (I) using the formula I = V/R:

I = 12 volts / 6 ohms

I = 2 amps

In electrical circuits, intensity refers to the current flowing through the circuit. In this case, with a voltage of 12 volts and a resistance of 6 ohms, the circuit has an intensity of 2 amps, meaning that 2 amperes of current flow through the circuit. (option c).

braking and acceleration

Explanation:

Weight transfer occurs as the vehicle's CoM shifts during automotive maneuvers. Acceleration causes the sprung mass to rotate about a geometric axis resulting in relocation of the CoM... Conversely, under braking, weight to towards the front of the car can occur.

The Weight transfer occurs during acceleration cornering and curves (steering) and braking, therefore all the given options are the correct answer

Weight transfer is the actual (relatively small) movement of the center of mass (CoM) of the vehicle with respect to the wheel axes caused by the displacement of the chassis as the suspension adjusts, or by the presence of cargo or liquids inside the vehicle, which causes a redistribution of the total weight of the vehicle among the individual tires.

There are three possible ways for weight transfers to happen: Acceleration. Deceleration. Steering.

In a rock-back move, the dancer steps backward while transferring all of her weight, then shifts her weight back to her front foot while maintaining her balance. When performing a rock forward, the dancer advances with full weight transfer and then shifts weight to the back foot while maintaining its position.

The acceleration due to gravity near the surface of the hypothetical planet is 3.02 m/s².

The formula for acceleration due to gravity is:

g = GM/r² Where, g = acceleration due to gravity G = universal gravitational constant M = mass of the planet r = radius of the planet

In this case, since the mass of the hypothetical planet is the same as that of Earth, we can use the mass of Earth instead of M.

Therefore, g is proportional to 1/r².

So, using the ratio of radii given (1.8), we can write:

r = 1.8 x r Earth, where r Earth is the radius of Earth.

Substituting this value of r in the formula for acceleration due to gravity, we get:

g = GM/(1.8 x r Earth)² = GM/(3.24 x rEarth²) = (1/3.24)GM/rEarth²

We know that the acceleration due to gravity on Earth (g Earth) is 9.8 m/s².

Therefore, we can calculate the acceleration due to gravity on the hypothetical planet (gh) as follows:

gh = (1/3.24) x g Earth = 3.02 m/s²

Thus, the acceleration due to gravity near the surface of the hypothetical planet is 3.02 m/s².

Answer: the total energy of the puck, ice surface, and surrounding air decreases to zero

Explanation:

A hockey puck slides across the ice and eventually comes to a stop because of friction between surface of the puck and ice surface.

Friction is a resistance to motion of the object. for example, when a body slides on horizontal surface in positive x direction, it has friction in negative x direction and that measure of friction is a frictional force. frictional force is directly proportional to the Normal(N). i.e. \(F_{fri}\) ∝ N

\(F_{fri}\) = μN where μ is called as coefficient of the friction. It is a dimensionless quantity.

When a body is kept on horizontal surface, its normal will be straight upward which is reaction of mg. i.e. N=mg.

Frictional force is equal to

\(F_{fri}\) = μmg

When hockey puck slides across the ice, friction between surface of puck and surface of ice produces resistance to the motion of the puck, due to resistance puck slow down slowly and eventually come to a stop. Motion and frictional force are opposite to each other. we can calculated the exact value of frictional force when we know the coefficient of friction between puck and ice surface.

Answer:

h = 17.83[m]

Explanation:

By means of the working equation which is equal to the product of force by distance, we can find the energy printed at the launch.

\(W=F*d\)

where:

W = work [J]

F = force = 3500 [N]

d = distance = 0.5 [m]

Now replacing:

\(W= 3500*0.5\\W=1750[J]\)

Now, this same work is converted to kinetic energy, necessary for the body to move with an initial velocity. And by energy conservation, we can say that kinetic energy is transformed into potential energy. That is, the kinetic energy will be equal to the potential energy.

\(W=E_{kin}=E_{pot}\)

where:

Ekin = kinetic energy [J]

Epot = potential energy [J]

Therefore:

\(1750 = m*g*h\\1750=10*9.81*h\\h = 17.83[m]\)

the new volume of the gas is 3.49 L when An external force performs 180 J of work as it compresses the gas at constant pressure.

An ideal gas is a theoretical gas comprised of numerous randomly moving point particles that do not interact with one another. The ideal gas notion is valuable because it obeys the ideal gas law, which is a simplified equation of state, and is susceptible to statistical mechanics analysis. Work is pressure times change in volume.

Given,

b) Immediately after the collision, two objects move together with a speed of v₀. The direction of motion is to the right, as A was moving to right before collision.

Momentum may be defined as the product of mass and velocity of any object.

(a) Before the collision, total momentum of the system is :

\(\mathrm{\rho = m_A \times v_A + m_B \times v_B}\)

\(\mathrm{m_A = m_B = M, v_A = 3v_0, \ and \ vB = -v_0}\) (since B is moving to the left).

Therefore, total momentum before the collision is:

\(\mathrm{\rho= M \times 3v_0 - M \times v_0 = 2M \times v_0}\)

(b) Immediately after the collision, the two objects move with the same velocity v. Total momentum of the system is: p' = (mA + mB)  ×  v = 2M  ×  v

As total momentum is conserved: p' = p

\(\mathrm{2M \times v = 2M \times v_0}\)
