Answer:

The formula is MgVg=MbVb.

which is 5×Vg=0.01×250.

5Vg=2.5.

Vg=2.5/5.

Vg=0.5m/s.

Answer: C) time

Explanation:

Answer:

  d = 845 m

Explanation:

This is an exercise in kinematics, specifically accelerated motion, let's use the equation

         v² = v₀² + 2 a d

since airplanes start from rest their initial velocity is zero

         v² = 2ad

         d = v2 / 2a

let's calculate

         d = 65² / (2 2.5)

         d = 845 m

this is the minimum distance from the track

Explanation:

Answer:

D

Explanation:

Given that the actor walk 5 steps forward, 9 steps left, and 2 steps backward to be standing over the trap

door.

Let first consider the steps forward and the steps backwards

The displacement = 5 - 2 = 3

That is, 3 steps forward.

Therefore,

The components of the actor's

motion from the starting position will be:

9 steps left and 3 steps forward

D is the correct answer.

Answer:

Since there is a gravitational pull, you wouldn't reach the other side. You'd probably be floating in the center of the earth.

[tex]\huge\boxed{Radiation}[/tex]

Explanation:

In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".

Answer:

[tex]\huge \boxed{\mathrm{\bold{C.} \ Radiation}}[/tex]

Explanation:

Microwaves heat food through the form of waves.

The waves are electromagnetic waves that transfer heat through the process of radiation.

Answer:

1440 m

Explanation:

Speed = Distance/Time

Distance = Speed × Time

               = 120 × 12

               = 1440m

Answer:

10000 Pa

Explanation:

Area = [tex]2 cm^2[/tex]

= 2/10000 = [tex]0.0002 m^2[/tex]

We know that,

Formula of pressure =

Pressure = Force/Area = 2N/0.0002 [tex]m^2[/tex] = 10000 Pascal

[tex]\boxed{\sf Pressure=\dfrac{Force}{Area}}[/tex]

[tex]\\ \sf\longmapsto Pressure=\dfrac{2}{0.0002}[/tex]

[tex]\\ \sf\longmapsto Pressure=10000Pa[/tex]

Answer: I’m not sure but the time and distance will be increasing while they required the distance time so my answer is ((A))

Explanation:

Answer:

clockwise is 2.5 Nm

Anticlockwise is 0.25 F Nm.

Explanation:

Moment is equal to force × distance

Answer:

Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil.

Answer:

25.632 m²

Given :

Steve walks from his house 5 km South then turns east and walks 2 km. Then he walks 9 km North to his older sister's house. She gives him a ride to his friend Fred's house 2 km West.

To Find :

The total distance covered by Steve .

Solution :

We know , distance is the actual measurement space between two points .

Now , total distance travelled by Steve is the sum of all distance travelled .

[tex]T=5+2+9+2\\\\T=18\ km[/tex]

So , total distance covered by Steve is 18 km .

Hence , this is the required solution .

The distance Steve traveled is mathematically given as

T=18Km

Question Parameters:

Steve walks from his house 5 km South then turns east and walks 2 km.

Then he walks 9 km North to his older sister's house.

Generally, the total distance has Steve traveled is mathematically given as

T=5+2+9+2

T=18Km

In conclusion, because the distance is the measure of space b/w two points the total distance traveled is

T=18Km

Answer:

Volume, [tex]V=696.55\ \mu m^3[/tex]

Explanation:

Given that,

The diameter of a human cell is 11 μm

It is enclosed by a membrane that is 4,4 nm thick.

We need to find the volume of the cell. The cell is spherical in shape. The volume of a sphere is given by the formula as follows :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

r is the radius of the sphere, r = 5.5 μm

So,

[tex]V=\dfrac{4}{3}\times 3.14\times (5.5)^3\\\\V=696.55\ \mu m^3[/tex]

So, the volume of the cell is [tex]696.55\ \mu m^3[/tex].

Answer:

a = F/m

Explanation:

So we have to isolate a, in order to do this we need to move m to the other side, and we do that by diving both sides by m, resulting in a = F/m

Answer:

v = 800 m/s

Explanation:

Given that,

Distance, d = 2400 m

Time, t = 3 s

We need to find the velocity of a rocket. Distance covered per unit time equals velocity. So,

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{2400\ m}{3\ s}\\\\v=800\ m/s[/tex]

So, the velocity of the truck is 800 m/s.

Answer:

418.6 J

Explanation:

We know the specific heat for water is 4.186 kJ/kg * °C, so this can also write as 4.186 J/g * °C, so the heat increases 5 C in this question, so you can get 4.186(J/g * C) * 5C * 20g = 418.6 J
