Answer:

Change in momentum: [tex]\langle -0.3,\, 0,\, 0\rangle\; {\rm kg \cdot m\cdot s^{-1}}[/tex].

Change in kinetic energy: approximately [tex](-0.2)\; {\rm J}[/tex].

Explanation:

Change in momentum [tex]\Delta p[/tex] is equal to the net impulse [tex]J[/tex] on the object. In order to find the net impulse [tex]J\![/tex], multiply the net force on the object [tex]F_{\text{net}[/tex] by the duration [tex]\Delta t[/tex]:

[tex]\begin{aligned} J &= F_{\text{net}}\, \Delta t \\ &= (1.5)\, \langle -0.2,\, 0,\, 0\rangle\; {\rm N\cdot s} \\ &= \langle -0.3,\, 0,\, 0\rangle\; {\rm kg \cdot m\cdot s^{-1}} \end{aligned}[/tex].

Since the change in momentum is equal to net impulse:

[tex]\Delta p = J = \langle -0.3,\, 0,\, 0\rangle\; {\rm kg \cdot m\cdot s^{-1}}[/tex].

Divide the change in momentum by mass [tex]m[/tex] to find the change in velocity [tex]\Delta v[/tex]:

[tex]\begin{aligned}\Delta v &= \frac{\Delta p}{m} \\ &= \frac{\langle -0.3,\, 0,\, 0\rangle}{0.8}\; {\rm m\cdot s^{-1}} \\ &\approx \langle -0.375,\, 0,\, 0\rangle\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

Thus, velocity has changed from [tex]u = \langle 0.9,\, 0,\, 0\rangle\; {\rm m\cdot s^{-1}}[/tex] to:

[tex]\begin{aligned} v &= u + \Delta v \\ &= \langle 0.9,\, 0,\, 0\rangle\; {\rm m\cdot s^{-1}} \\ &\quad + \langle -0.375,\, 0,\, 0\rangle\; {\rm m\cdot s^{-1}} \\ &= \langle 0.525,\, 0,\, 0\rangle\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

The initial kinetic energy (a scalar) was:

[tex]\begin{aligned}(\text{KE, initial}) &= \frac{1}{2}\, m\, {(\| u\|_{2})}^{2} \\ &\approx \frac{1}{2}\, (0.9^{2})\; {\rm J} \\ &=0.324\; {\rm J}\end{aligned}[/tex].

The new kinetic energy would be:

[tex]\begin{aligned}(\text{KE}) &= \frac{1}{2}\, m\, {(\| u\|_{2})}^{2} \\ &\approx \frac{1}{2}\, (0.525^{2})\; {\rm J} \\ &= 0.11025\; {\rm J}\end{aligned}[/tex].

Hence, the change in kinetic energy would be:

[tex]\begin{aligned} &(\text{KE}) - (\text{KE, initial}) \\ \approx\; & 0.324\; {\rm J} - 0.11025\; {\rm J}\\ \approx \; & (-0.2)\; {\rm J} \end{aligned}[/tex].

An object has a mass of 15 g and a volume of 5 cm³, the density of the object is: 3 g/cm³

To calculate the density of an object with a mass of 15 g and a volume of 5 cm³, you can use the equation

Density = Mass/Volume.

Using this equation, the density of the object is 3 g/cm³.

Density is a measure of how much mass is contained in a given volume of an object. The higher the density, the more mass is contained in the same volume. Mass is measured in grams (g) while volume is measured in cubic centimeters (cm³).

To calculate the density of an object, you must divide the mass of the object (measured in grams) by the volume of the object (measured in cm³).

In this example, the mass of the object is 15 g and the volume of the object is 5 cm³. So, the density of the object is calculated by dividing 15 g by 5 cm³, which gives us a result of 3 g/cm³.

In summary, to calculate the density of an object, you must divide the mass (measured in g) by the volume (measured in cm³). In this example, the mass of the object is 15 g and the volume of the object is 5 cm³, so the density of the object is 3 g/cm³.

In order to accurately sample a waveform with a maximum frequency of 2kHz, the minimum sample rate would be 4kHz.

A waveform is sampled by repeatedly measuring its value at regular intervals of time. The process of sampling a waveform is known as sampling. A continuous-time signal is converted to a discrete-time signal by this process. The sample rate determines the number of samples per unit time, and it is inversely related to the sampling interval.

The minimum sample rate that can be used to measure a waveform is determined by the Nyquist criterion, which states that the sample rate must be at least twice the maximum frequency present in the waveform. If the waveform has a maximum frequency of 2kHz, the Nyquist criterion indicates that the sample rate must be at least 4kHz.

Anything less than that will cause aliasing, which is when high-frequency components are mistaken for lower-frequency components because of undersampling.

Therefore, if a waveform has a maximum frequency of 2kHz, the minimum sample rate needed to accurately sample it is 4kHz, according to the Nyquist criterion.

When a truck is moving at constant velocity, and a rock is dropped from the midpoint of the ceiling and strikes the floor below, the rock hits the floor at exactly below the midpoint of the ceiling. The correct option is (A) exactly below the midpoint of the ceiling.

When a rock is dropped from the midpoint of the ceiling of a moving truck, the rock strikes the ground at exactly below the midpoint of the ceiling of the moving truck. This is because of the following reason:

When a truck is moving at constant velocity, everything in it is also moving at a constant velocity relative to the earth, including the rock. Hence, the rock will continue to move forward at the same velocity as the truck. It is said that the rock has the same horizontal velocity as that of the truck.

Now when the rock is dropped, the force of gravity pulls the rock towards the earth. Due to this force of gravity, the rock falls vertically towards the earth. Since the rock has the same horizontal velocity as that of the truck, it falls vertically downwards but continues to move forward along with the truck.

Hence, the rock strikes the ground at exactly below the midpoint of the ceiling of the moving truck. Therefore, the correct answer is option (A).

The single most important property of a star that determines its evolution is its mass.

A star's mass determines its internal temperature, pressure, and nuclear reactions, which drive its energy production and ultimately its evolution. Low-mass stars, like red dwarfs, have relatively low internal temperatures and undergo a slow process of fusion that can last for trillions of years. On the other hand, high-mass stars, like blue giants, have much higher internal temperatures and undergo fusion much more quickly, leading to a shorter lifespan.

Two soccer balls were kicked down the field, Ball A and Ball B. Ball A was kicked farther than Ball B, but Ball B reached a higher height than Ball A. It can be determined that the ball that spent more time in the air was Ball B.

Why Ball B spent more time in the air than Ball A?

Ball B was kicked into the air at a higher angle, meaning it travelled upwards for a longer amount of time. The ball's horizontal velocity would have been lower than Ball A's, causing it to travel a shorter distance horizontally.

However, the additional time Ball B spent travelling upwards and falling back down would have compensated for the shorter horizontal distance travelled, allowing it to remain in the air for longer than Ball A.

Ball A's flight time would have been shorter than Ball B's flight time because of its high horizontal velocity. Because Ball B had a higher initial upward velocity, it travelled higher in the air and took longer to fall back down, resulting in a longer flight time. As a result, Ball B spent more time in the air than Ball A.

The forces that act on the bicycle + rider system are Gravity, normal force, static friction, kinetic friction, air resistance, and rolling friction.

The force that pulls objects toward the center of a planet or another body is called gravity. All the planets are maintained in their orbits around the sun due to the force of gravity.

The force surfaces exert to prevent solid objects from passing through one another is known as the normal force.

When there is no relative motion between the object and the surface, a body is subject to a particular form of friction force known as static friction.

The forces that oppose the motion of an object as it travels through the air are known as air resistance.

A force called rolling friction opposes a rolling object's motion on a surface. Rolling resistance is another name for rolling friction.

Hence, Gravity, normal force, static friction, kinetic friction, air resistance, and rolling friction are the forces acting on the bicycle and rider system.
