The magnitude of the unknown height of the projectile is determined as 16.1 m.

The magnitude of the height of the projectile is calculated as follows;

H = u²sin²θ/2g

H = (36.6² x (sin 29)²)/(2 x 9.8)

H = 16.1 m

Thus, the magnitude of the unknown height of the projectile is determined as 16.1 m.

Answer:

D.

Explanation:

acceleration in the z component = velocity in z component / time. The question states velocity in z component is zero. Therefore, acceleration in z component = 0/time = 0.

Now the question does not specify whether the other velocity vectors (x or y) is zero or not. So its D.

The pendulum have the least potential energy at the point C between point A and B because it is lower in height as compared to other points.

Potential energy is the energy held by an object because of its position. If the object is present at a certain height, it has more potential energy as compared to object which is lower in height.

So we can conclude that the pendulum have the least potential energy at C point that is between point A and B.

In a longitudinal wave, the propagation of energy is in the direction of the motion, while in a transverse wave the propagation of energy is perpendicular to the direction of motion.

Longitudinal wave is a wave which moves in the direction from where it was started. It has a compression (increased intensity) of the medium particles and a rarefaction ( reduced intensity).

Transverse wave is wave that travels perpendicular or at right angles to the direction from where it was started.

The main differences between longitudinal wave and Transverse wave are:

Answer: 2, 3, and 5

Explanation:

Ultimate tensile strength is the maximum stress that a material can withstand just before fracture.

Stress is defined as the force acting per unit area. It is denoted by Sigma(σ)

When a body is undergoing stretch by applying a pull force, it stretches more and more until it reaches its elastic limit. A point comes when the body no more stretches and breaks or fractures at bottle neck formation. This strength of any material is known as Ultimate breaking Stress or Ultimate tensile strength.

Thus, Ultimate tensile strength is the maximum stress that a material can withstand just before fracture.

Answer:

Answer:

Approximately [tex]122.625\; {\rm m}[/tex] (assuming that [tex]g = 9.81\; {\rm m\cdot s^{-2}}[/tex], the ball was launched from ground level, and that the drag on the ball is negligible.)

Explanation:

Let [tex]v_{0}[/tex] denote the velocity at which the ball was thrown upward.

If the drag (air friction) on the ball is negligible, the ball would land with a velocity of exactly [tex](-v_{0})[/tex]. The velocity of the ball would be changed from [tex]v[/tex] to [tex](-v_{0})\![/tex] (such that [tex]\Delta v = (-v_{0}) - v_{0} = (-2\, v_{0})[/tex]) within [tex]t = 10\; {\rm s}[/tex].

Also because the drag on the ball is negligible, the acceleration of the ball would be [tex]a = -g = -9.81\; {\rm m\cdot s^{-2}}[/tex]. Thus:

[tex]\Delta v = a\, t = 10\; {\rm s} \times (-9.81\; {\rm m\cdot s^{-2}}) = -98.1\; {\rm m\cdot s^{-1}}[/tex].

Since [tex]\Delta v = (-2\, v_{0})[/tex]:

[tex]-2\, v_{0} = \Delta v = -98.1\; {\rm m\cdot s^{-1}[/tex].

[tex]\begin{aligned}v_{0} &= \frac{-98.1\; {\rm m\cdot s^{-1}}}{-2}= 49.05\; {\rm m \cdot s^{-1}}\end{aligned}[/tex].

The ball reaches maximum height when its velocity is [tex]v_{1} = 0\; {\rm m\cdot s^{-1}}[/tex]. Apply the SUVAT equation [tex]x = ({v_{1}}^{2} - {v_{0}}^{2}) / (2\, a)[/tex] to find the displacement [tex]x[/tex] between the original position (ground level, where [tex]v_{0} = 49.05\; {\rm m\cdot s^{-1}}[/tex]) and the max-height position of the ball (where [tex]v_{1} = 0\; {\rm m\cdot s^{-1}}[/tex].)

[tex]\begin{aligned}x &= \frac{(0\; {\rm m\cdot s^{-1}})^{2} - (49.05\; {\rm m\cdot s^{-1}})^{2}}{2 \times (-9.81\; {\rm m\cdot s^{-2}})} \\ &\approx 122.625\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

''states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.''

Archimedes principle equation is given as

buoyant force = density of fluid x volume of displaced fluid x acceleration due to gravity. or

Fb=-density*gravity*volume

For example, a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight.

Answer:

Archimedes principle states that"When a body is totally or partially immersed in a liquid,it experience an upthrust which is equal to the weight of the liquid displaced"

This shows that the weight of liquid displaced when a certain object is placed in water is equal to the weight of the object.

Answer:

[tex]750\; {\rm m\cdot s^{-1}}[/tex].

Explanation:

The distance between two adjacent nodes of a standing wave is equal to one-half (that is, [tex](1/2)[/tex]) the wavelength of this wave.

Let [tex]\lambda[/tex] denote the wavelength of the standing wave in this question. The distance between two nodes of this wave is [tex]0.25\; {\rm m}[/tex], meaning that [tex](1/2)\, \lambda = 0.25\; {\rm m}[/tex]. Thus, [tex]\lambda = 2 \times 0.25\; {\rm m} = 0.50\; {\rm m}[/tex].

Given that [tex]f = 1500\; {\rm Hz}[/tex] is the frequency of the waves that formed this standing wave, the speed of these waves would be:

[tex]\begin{aligned}v &= \lambda\, f \\ &= 0.50\; {\rm m} \times 1500\; {\rm Hz} \\ &= 0.50\; {\rm m} \times 1500\; {\rm s^{-1}} \\ &= 750\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

Answer:

A change in odor

Explanation:

if a volume of air is warmed it expands due to increased translational kinetic energy as it expands it will start to cool.

We can then conclude that at constant pressure, temperature and volume are directly proportional: temperature increases, volume increases; decrease temperature, decrease volume.

In this case, the higher the temperature, the greater the kinetic energy that acts on the molecules of this gas, so when the gas expands, these molecules find more space and collide less, which will cause the gas to cool.
