Which of the following describes a change in energy that occurs as an acorn falls from a tree toward the ground

Answer:

Yes, acceleration and force are directly proportional to each other.

Explanation:

The force acting on an object is given by :

F = ma

Where

m is mass

a is acceleration

It can be clear from the above formula that the acceleration and the force are directly proportional to each other.

Explanation:

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.

(1) The kinetic energy of the golf ball is 37.82 Joules,

(2) The kinetic energy of the F-22 jet fighter is 1.8 × 10¹⁰ Joules.

(3) The potential energy of the  F-22 jet fighter is 9.8 × 10⁹ Joules .

Kinetic energy is a type of power that a moving object or particle possesses. When an object undergoes work, which involves the transfer of energy, by exerting a net force, the object accelerates and consequently obtains kinetic energy.

Given:

The velocity of the ball, v = 41 m / s,

The mass of the golf ball, m = 0.045 kg,

(1)  Calculate the kinetic energy as shown below,

KE = 1 / 2 × 0.045 × 41²

KE  = 37.82 Joules

(2)  Calculate the kinetic energy of the F-22 jet fighter as shown below,

KE = 1 / 2 × 600² × 100000

KE = 1.8 × 10¹⁰ Joules

(3)  Calculate the potential energy of the jet as shown below,

PE = 100000 × 9.8 × 10000

PE = 9.8 × 10⁹ Joules

Explanation: the numbers are cool

(2). a = v/t

but v =s/t

a =s/t÷t

a=s/t×t

a=s/t²

a=220/5.21²

a=8.10m/s²

Explanation:

For the question 1, just imput the value of t into the equation

Answer:

Exactly 27 m/s

Explanation:

P=mv

P(cannon)=2.7*1.7

P(cannon)=4.59 kg*m/s

P(cannon)=P(tshirt)

4.59=0.17*v

v=27 m/s

The basketball's angular velocity ω at time t is

ω = 27 rad/s + (-0.15 rad/s²) t

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

t = (27 rad/s) / (0.15 rad/s²)

t = 180 s

In this time, the ball would undergoes an angular displacement θ of

θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²

Plug in t = 180 s and solve for θ :

θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad

One complete revolution corresponds to a turn of 2π rad, so the ball makes

(2430 rad) / (2π rad/rev) ≈ 386.747 rev

or about 387 revolutions as it slows down.

YESSS. my education went down hill since the pandemic :(

Explanation:

Answer:

Higher frequency.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the speed of a sound is given by the formula:

[tex] Speed = wavelength * frequency [/tex]

Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.

A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.

Hence, shrill sound is of higher frequency.

Answer:

Explanation:

Consider an endless sheet of uniform charge thickness per unit area [tex]\sigma[/tex]  

For a boundless sheet of charge, the electric field will be opposite to the surface. In this way, just the closures of a round and hollow Gaussian surface will add to the electric transition. For this situation, around and hollow Gaussian surface opposite to the charge sheet is utilized. The subsequent field is a large portion of that of a conductor at harmony with this surface charge thickness.  

By balance, we expect the electric field on one or the other side of a plane to be an element of x just to be guided typical to the plane and to point away from/towards the plane contingent upon whether, [tex]\sigma[/tex] is positive/negative.

According to the law;

[tex]2EA = \dfrac{q_{enc}}{\varepsilon_o}[/tex]

[tex]where; \ q_{enc} = total \ enclosed charge = \sigma A \\ \\ thus; \\ \\ 2EA = \dfrac{\sigma A}{\varepsilon_o} \\ \\ E = \dfrac{\sigma}{2 \varepsilon _o}[/tex]
