Im not doing the math-

Answers

Answer 1

The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Answer 2

The answer is 0.36 m/s credit to the guy above me (give him Brainlyist) but I also had to do this assessment.

Explanation:

Conrad recently built a new home but soon realized that this activity impacted the shoreline. He would like to reduce the impact that he has had on the land while still keeping his home safe from high winds and powerful storms.

Which possible solution should he choose?

A. He should create a sand dune.

B. He should move his home inland.

C. He should plant vegetation.

D. He should create marshes.

Answers

Answer:

C. He should plant vegetation.

Explanation:

Planting vegetation can help reduce the impact of shoreline erosion by stabilizing the soil and preventing it from being washed away by water. The roots of the plants help to hold the soil in place, and the leaves and stems can absorb some of the energy from waves and storm surges, reducing their erosive force.

Creating a sand dune or marsh can also help to reduce shoreline erosion, but these options may not be feasible for Conrad's particular situation. Creating a sand dune may require large amounts of sand and ongoing maintenance, and creating a marsh may require significant modifications to the existing shoreline.

Moving the home inland may also not be a desirable solution, as it could be expensive and may not provide adequate protection from high winds and storms.

Therefore, planting vegetation is the most practical and effective solution for Conrad to reduce the impact of his home on the shoreline.

C, he should plant vegetation

Which object has the most kinetic energy?

A. a train that is stopped
B. a car moving at a slow speed
C. a train moving at a slow speed
D. a car that is stopped at the top of a hill

Answers

C

Explanation: kinetic energy means that the object is moving, automatically eliminating A and D since they are both stopped. The formula for kinetic energy is KE=1/2m(v^2) (m= mass and v= velocity). Since the train has more mass than the car, the train has more kinetic energy.

C is the right answer because train has more mass than car

Explanation:

Hope it helps you!!

Marco put a pot of water on to boil eggs. Half an hour later, he returned to find the pot dry. This is an example of vaporization. Hence option 4 is correct.

What is vaporization?

Vaporization is defined as the process by which a liquid or solid is transformed into a gas at any temperature. Only the liquid's top experiences evaporation, whereas the liquid's bulk experiences boiling. When anything turns from a liquid to a gas, evaporation occurs. Water evaporates when it is heated. The molecules vibrate and travel so swiftly that they release water vapor molecules into the atmosphere.

When you boil a pot of water, you can observe evaporation. Evaporation and boiling are the two processes that cause vaporization. When water is exposed to sunshine, it evaporates, turning into vapor that rises into the atmosphere.

Thus, Marco put a pot of water on to boil eggs. Half an hour later, he returned to find the pot dry. This is an example of vaporization. Hence option 4 is correct.

Why is it important to know how the sun's energy affects the lower atmosphere if you are planning to harness the power of moving air?

Answers

it determines pressure and determines the movement of the wind.

It is important to know the affects of temperature on pressure and thereby on winds. At high temperature, the pressure will be high and thus, the winds will pass from that area.

What is winds?

Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.

Air pass from high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.

Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.

D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it
