Can someone tell me the answer of this question?

Answer:

Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement. For example, if you add the same amount of sugar to a cup of hot tea and a cup of iced tea, the sugar will dissolve faster in the hot tea.

Answer:

8100 g

Explanation:

8.1 kg × 1000

= 8100 g

Answer:

8,100 Grams

Explanation:

To change Kilograms to Grams, you multiply the mass value by 1000.

So, 8.1kg x 1000 = 8,100g.

Answer:

4m/s^2

Explanation:

using the formula a = (v_f - v_i) / Δt we can use final velocity, initial velocity, and accel. time to calculate the accel. rate

In this problem it would be a=(26m/s - 10m/s) / 4s

our answer would be 4m/s^2

Answer:9.82 m

Explanation:

As we know from equation of motion

S=v*t +0.5 a t^2

Know s=H/2

a =9.82

t=1

V=0

Plugging the values

H*0.5=0+0.5*9.82*1^2

H=9.82 m

Answer: give up because nothing can be done.

Explanation:

You would have to give up because you have taken on an impossible task. And nothing can be done because there is no known means available to you to measure or observe what is happening outside the spaceship. And as a result this has made it an impossible task knowing the velocity of the ship or finding out.

Answer:

Explanation:

To get the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle, we will have to resolve the force perpendicular to the wrench. Torque is the turning effect of a body or force about a point. It is similar to moments.

Torque = Force * radius

Note that the force must be perpendicular to the wrench. On resolving the force perpendicularly to the wrench, we will have to resolve the force to the vertical.

Fy = Fsinθ

Fy = 10sin30°

Fy = 10 * 0.5

Fy = 5N

Torque = Fy * r

Given Fy = 5N and r = 20cm = 0.2m

Torque = 5 * 0.2

Torque = 1Nm

Hence the magnitude of the force would require to just loosen the nut, if the force apply perpendicularly at the end of the handle is 5N

Answer:

The length of days and nights change with the seasons.

Explanation:

Distance from the equator along with the tilt of Earth's rotational axis contributes to day and night period differences. Daylight hours or the period of sunlight exposure vary due to the inclined axis of the latitudes. In the northern hemisphere during summers, the tilt of the axis is towards the sun which brought more sunlight to the exposed region. And therefore the length of day hours is more than the southern hemisphere which at the same time will be tilted away from the sun.

Explanation:

At t = 0 , X = -3 m

At t = 8s  , X = + 3 m .

At t = 16s  , X = + 3 m

At t = 24 s , X = + 9 m

The displacement of the car between 8 seconds and 24 seconds is 6 m.

The given parameters:

The displacement of the car between 8 seconds and 24 seconds is calculated as follows;

the position of the car at 8 seconds = 3 m

the position of the car at 24 seconds = 9 m

The displacement of the car = 9m - 3m = 6 m

Thus, the displacement of the car between 8 seconds and 24 seconds is 6 m.

Answer:

Both technicians are correct

Explanation:

In electromagnetic induction, the induced voltage can be increased by increasing the relative speed between the conductor and the magnetic line of force, by increasing the strength of the magnetic field, which increases the magnetic lines of force, Increase the strength of the magnetic field, so there are more flux lines, and also by increasing the angle between the flux lines and the conductor to a maximum of 90 degrees.

Answer:

A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.

Answer:

The speed of the flow of water in the river is 4 m/s.

Explanation:

Given that,

Speed of man = 5 m/s

If this man swims crosses a specific river his speed is 3 m/s.

If he takes the minimum time to cross the river

Let the speed of flow of water be [tex]v_{r}[/tex]

We need to calculate the speed of the flow of water in the river

Using formula for velocity

[tex]v_{rs}^2=v_{r}^2+v_{s}^2[/tex]

[tex]v_{r}^2=v_{rs}^2-v_{s}^2[/tex]

Where, [tex]v_{s}[/tex] = velocity of swimmer

[tex]v_{sr}[/tex] = relative velocity

[tex]v_{r}[/tex] = velocity of river

Put the value into the formula

[tex]v_{r}^2=5^2-3^2}[/tex]

[tex]v_{r}=\sqrt{5^2-3^2}[/tex]

[tex]v_{r}=4\ m/s[/tex]

Hence, The speed of the flow of water in the river is 4 m/s.

Answer:

Explanation:

Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.

Answer:

The above has the correct statement

Explanation:

The coyotes have the same energy of motion, even if they are running at different speeds.

Answer:

Kinetic energy=1/2 mv^2.

which is 1,000,000,000=1/2×90,000×v^2.

1000000000=45,000v^2.

v^2=222.22.

v=√222.22.

v=14.9~15m/s.

The speed of a 90,000 kg airplane with a kinetic energy of one billion Joules would be 149.07 m/s

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.

Total mechanical energy is s the sum of all the kinetic as well as potential energy stored in the system.

ME = KE + PE

As given in the problem we have to calculate the speed of an airplane with a mass of 90,000 kg and kinetic energy of one billion Joules.

m= 90000 kg

K.E = 1 billion Joules

     = 1,000,000,000 Joules

The total kinetic energy

KE = 1/2mv²

By substituting the respective values in the formula of kinetic energy

1,000,000,000 J = 1/2×90000 ×v²

v² = 1,000,000,000 ×2/90000

v² = 22222.222

v =149.07 m/s

Thus, the speed of a 90,000 kg airplane with a kinetic energy of one billion Joules would be 149.07 m/s
