Answers

Answer 1

Answer:

Explanation:

1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.

  Since line CD is a straight line, therefore, slope = 0

  Hence instantaneous velocity = 0

2). Distance of the object when it moves from 0 to 9 seconds

    = Distance traveled from (A to B + B to C + C to D + D to E)

    = 3 + (3 + 0.5) + 0 + 0.5

    = 7 m

3). Displacement = Distance between initial and the final positions of the object

    = 3 - 0

    = 3 m

4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]

                                 = [tex]\frac{0.5}{5}[/tex]

                                 = 0.1 m per sec

5). Direction changes have been seen at t = 2 sec and t = 4 sec.

   Hence object changed its direction of travel 2 times.

Help me please it due today at 11:59 pleasss

Answers

Answer:

see below

Explanation:

1. density = mass / volume

2. kg/mL,  g/cm³

3. volume = mass / density

4. mass = density x volume

5.  

d = m / v

d = 32.9 g / 45.78 mL

d = 0.72 g/mL

6.

vol = m / d

vol = 0.62 g / 120g/cm³

vol = 0.00517 cm³

7.

m = v * d

m = 2.07 g/mL * 60.9 mL

m = 126.063 g

The fastest helicopter, the Westland Lynx, can travel 3.33 km in the forward direction in just 30.0 s. What is the average velocity of this helicopter? Express your answer in both m/s and km/hr.

Answers

Answer:

The value in m/s [tex]v_{a} = 111 \ m/s [/tex]

The value in km/h [tex]v_{a} = 400\ km/h [/tex]

Explanation:

Generally the average velocity of the helicopter is mathematically represented as

[tex]v_{a} = \frac{\Delta D}{ t}[/tex]

substituting [tex]3.33 km = 33.3*10^3\ for\  \Delta D[/tex] and  30.0 s for  t

We have

         [tex]v_{a} =  \frac{33.3 *10^{3}}{ 30}[/tex]

=>     [tex]v_{a} =  111 \  m/s [/tex]

Now converting to km/h

      [tex]v_{a} =  111  *  \frac{3600  *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}} [/tex]

=>  [tex]v_{a} = 400\  km/h [/tex]

Which of the following is most likely to happen when energy is transferred to an object A) the object will stay exactly the same B)The object Will begin to move C)the force on the object will decrease D) the mass of the object will increase

Answers

Answer:

B. the object will begin to move

Explanation:

If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"

When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.

What is energy transfer?

Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.

When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.

The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

A 0.5 kg yellow bouncy ball rolls to the right at a speed of 8 m/s while a 0.25 kg blue bouncy ball rolls
to the left towards it with a speed of 4 m/s. After the collision, the blue bouncy ball rolls to the right
with a speed of 12 m/s. How fast is the yellow ball rolling and in what direction?

Answers

Explanation:

Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.

After collision, blue ball travels 12 m/s.

Using conservation of Linear Momentum :

m1u1 + m2u2 = m1v1 + m2v2

0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12

v1 = 0 m/sec i.e. Yellow ball comes to rest.

Explanation:

The two velocities form a right triangle.  Use Pythagorean theorem to find the magnitude of the resultant velocity.

v² = (-15 m/s)² + (-7.5 m/s)²

v = 16.77 m/s

Use trig to find the angle.

Irene was investigating the behavior of gases at certain conditions. Which would most likely cause an increase in the rate of collisions between gas molecules in a container?

Answers

Answer:

Increase in temperature

Increase in pressure

Explanation:

For the rate of collisions to increase, It can happen in various ways

1. The gasses can be made to move faster: This can be done by increasing their temperature. An increase in the temperature of the gases directly relates to a corresponding increase in their kinetic energy. This means that the molecules of the gases can move with a greater velocity, which will increase collision rates.

2. The volume of the container can be reduced: Consider this; If the container is made smaller, the molecules of the gases will have less space to move about. This means that they will be bumping into the walls of the container more frequently. This reduction in volume leads to an increase in the pressure of the gas. This is exactly what happens in a piston-cylinder assembly

The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure

Reasons for increasing the rate of collisions:

1. In the case when the gasses should be quick faster, due to this, the temperature should be increased. In this, the gases molecules should be moved have high velocity

2, Here the container volume should be decreased. Due to this, the volume should be decreased that results in the increment of the gas pressure.

Therefore, The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure

use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5

Explanation:

u = 13.5 m/s

Need help! Photo says all! Will mark brainliest :)

Answers

Answer:

C-D

Explanation:

As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.

Divide 6 meters by 3 seconds to find the speed:

6 ÷ 3 = 2 m/s

B-C is not moving due to a straight line as said in the graph, so speed is

0 m/s.

There is also C-D since the car traveled from a distance of 9 meters

(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)

Divide 9 meters by 3 seconds to get the speed:

9 ÷ 3 = 3 m/s

Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.

A-D does not count here as the line has no connection between point A and point D.

A fleeing student covered a distance of 210 meters in 35 seconds. what is the student's speed in meters/second? what is the student's speed in meters/minute?

Answers

Explanation:

Given that,

A student covered a distance of 210 meters in 35 seconds.

We need to find the student's speed in meters/second and also in meters/minute.

Speed, v = distance (d)/time (t)

So,

[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]

We know that, 1 minute = 60 seconds

[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]

Hence, the student's speed is 6 m/s or 360 meters/minute.
