Answer:

When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

Answer:

Angular acceleration [tex]= 0.167[/tex] rad/s^2

Explanation:

Given

Initial Angular velocity (w1) [tex]= 5[/tex] rad/s

Final Angular velocity (w2) [tex]= 0[/tex] rad/s

Time taken to change velocity from w1 to w2 [tex]= 30[/tex] seconds

Angular acceleration is equal to the change in angular velocity to the time taken for making thing change

Hence, Angular acceleration

[tex]\frac{w_2 -w_1}{t} \\\frac{5-0}{30}\\0.167[/tex]rad/s^2

Answer:

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

Answer:

metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.

B. measure the distance that the plane flew and record it

Explanation:

Answer:

3.8 × 108 m

Explanation:

Use formula: v^2 = G x m central / r

G = 6.77 e-11

Also, it was right on Edge.

Good luck!

The distance between Earth and its moon is 3.8×10⁸ m.

A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path.

It is "a force by which bodies are dragged or driven, or in any manner tend, towards a point as to a center," according to Isaac Newton.

Given parameters:

Mass of the Earth: M = 6.0 × 10²⁴ kg.

Mass of the moon: m = 7.3 × 10²² kg.

Moon's tangential speed: v = 1,025 m/s

Let the distance between the center of Earth and the moon is r.

Hence,

GMm/r² = mv²/r

r = GM/v²

= 6.7 × 10 ⁻¹¹ × 6.0 × 10²⁴ / (1,025)²

= 3.82×10⁸ m.

Hence, by subtracting Earth's radius = 6.4 x 10⁶ m, we get, the distance between Earth and its moon is 3.8×10⁸ m.

Probable Reason - Break in filament of electric bulb

Explanation:

An electric bulb might not glow even if it is connected to the cell, possibly  because of break in the filament of electric bulb. As, break in bulb's filament implies break in flow of electric current - between electric cells' terminal.

An evident example of this is , a fuse bulb doesn't light up as the current doesn't pass through filament.

Answer:

V=3.57 × 10^6 m/s

hope it is helpful..

The speed of the proton in the magnetic field is 3.57×10⁶ m/s.

To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.

               F=q×v×B

  where, q= charge of the particle

              v= speed of the particle

              B= magnetic field

       v=F/(q×B)

                  F=2.40×10⁻¹⁴N

                  q= 1.6×10⁻¹⁹C

       Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)

                   = 3.57×10⁶ m/s.

Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

Answer:

a) 361.7 Hz

b) 318.1 Hz

c) 29.3 m/s

Explanation:

a) Speed of sound in 20 degrees celcius is 343 m/s.

Use v=wavelength*frequency to find wavelength.

343=wavelength*340

wavelegth=1.009 meters

Relative speed of waves to observer A = 343+22 = 365 m/s

Plug it back in.

365=1.009*F

F=361.7 Hz

b) Relative speed of waves to observer B = 343-22 = 321 m/s

Plug it back in.

321=1.009*F

F=318.1 Hz

c) STATIONARY CAR, so 369Hz=v/1.009. v=372.3, 372.3-343=29.3m/s!

Answer:

h = 4T/dgr

Explanation:

Using Laplace law for spherical bubble, the pressure difference P'- P = 4T/r where T = surface tension and r = radius of sphere.

Now, the pressure difference on the hollow sphere P' - P = dgh where d = density of liquid, g = acceleration due to gravity and h = maximum depth to which sphere must be immersed.  

So dgh = 4T/r

h = 4T/dgr

Answer:

Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
