If there is "waste" energy, does the Law of Conservation of Energy still apply? please don't type something random if so i'll just report it.​

Atom A has 10 protons, 12 neutrons, and 10 electrons, while Atom B has 10 protons, 10 neutrons, and 12 electrons.

Atom A and Atom B are not isotopes of each other. Isotopes are atoms of the same element that differ in the number of neutrons but have the same number of protons. In this case, Atom A and Atom B have different numbers of protons, which means they are not isotopes of each other.

The number of protons determines the element, and since Atom A and Atom B have different numbers of protons, they belong to different elements.

Isotopes, on the other hand, have the same number of protons but differ in the number of neutrons.

This variation in the number of neutrons gives isotopes different atomic masses while retaining the same chemical properties.

However, Atom A and Atom B do not fulfill this criterion, so they cannot be considered isotopes of each other.

Answer:

Explanation:

Let the required depth be d .

Sound will first travel trough 480 m deep lake . Then it will enter granite layer .   Sound travelling through granite will reach oil level , get reflected and come back to the surface of lake as echo . Total time taken by sound to travel total distance  is .93 s

Total distance = 2d + 2 x 480 m

= 2d + 960 m

speed of sound in granite is given as 6000 m / s and speed through water is 1480 m /s

total time taken

= 2d / 6000 + 960 / 1480 = .93

2d / 6000 + .6486 = .93

2d / 6000 = .2814

d= 844.2 m

a) The amplitude is 0.143 m

b) The modulus of the maximum velocity is 2.79 m/s

c). The position when the speed is 1.5 m/s = -0.061 m

d) The modulus of the maximum acceleration= 6.99 m/s^2.

(a) To find the amplitude A, we can rearrange the formula for mechanical energy:

A = √(2E/k)

= √(2*0.2/46)

= 0.143 m.

(b) The modulus of the maximum velocity is achieved when the block passes through the equilibrium position (i.e., x=0) and is given by vmax = √(k/m) * A

= √(46/0.117) * 0.143

= 2.79 m/s.

(c) To find the position when the speed is 1.5 m/s, we can use the velocity formula and solve for x:

1.5 = √(k/m) * √(A^2 - x^2)

1.5^2 = k/m * (A^2 - x^2)

x^2 = A^2 - (m/k) * (1.5^2)

x = +/- √(A^2 - (m/k) * (1.5^2))

Since the block is moving to the left when the speed is 1.5 m/s, we take the negative root:

x = -√(0.143^2 - (0.117/46) * (1.5^2))

= -0.061 m.

(d) The modulus of the maximum acceleration is achieved when the block is at the equilibrium position (i.e., x=0) and is given by amax = w^2 * A = sqrt(k/m) * A

= √(46/0.117) * 0.143

= 6.99 m/s^2.

Explanation:

The instantaneous velocity at 60 m is zero, at - 40 m is - 1 m / s, at 15 s is zero and at 25 s is 0.8 m / s if Displacement (m) 0 20 40 40 80 80 60 400 Time (s) 10 10 20 30 40 50 60 70 80.

Instantaneous velocity = Position with respect to time / Time

1 ) At d = 60 m, the instantaneous velocity is zero because the car is at rest.

2 ) At d = - 40 m, t = 40 s

Instantaneous velocity = - 40 / 40

Instantaneous velocity = - 1 m / s

3 ) At t = 15 s, d = 60 m

At 60 m, the car is at rest, so the Instantaneous velocity is zero

4 ) At t = 25 s, d = 20 m

Instantaneous velocity = 20 / 25

Instantaneous velocity = 0.8 m / s

Instantaneous velocity of a given curve in a position-time graph can be found by drawing a tangent to the curve and finding the slope of the tangent. Instantaneous velocity = 0

Instantaneous velocity = - 1 m / s

Instantaneous velocity = 0

Instantaneous velocity = 0.8 m / s

Therefore, The instantaneous velocity at 60 m is zero, at - 40 m is - 1 m / s, at 15 s is zero and at 25 s is 0.8 m / s if Displacement (m) 0 20 40 40 80 80 60 400 Time (s) 10 10 20 30 40 50 60 70 80.

I₂ = 4.0 kgm², ω₂ = 15.0 rad/s

Angular momentum conservation:

I₁ω₁ + I₂ω₂ = (I₁ + I₂)ω

The right sphere will acquire an equal and opposite net positive charge to balance the negative charge on the left sphere.

Since the left sphere is attracted to the positively charged rod, it means that the left sphere acquires a temporary negative charge due to induction.

The positive charge on the rod repels electrons in the left sphere, causing them to move away from the rod side and accumulate on the opposite side, resulting in a net negative charge on the left sphere.

According to the principle of charge conservation, the net charge on the system must remain zero. Therefore, the right sphere acquires an equal and opposite net positive charge to balance the negative charge on the left sphere.

Where t is time in seconds after reaching the first checkpoint.

Part b:

Acceleration = change in velocity/time

v2: final velocity, v1: initial velocity, t: time

Let's keep track of all the variables we know:

v2 = 32 m/s, v1 = 20 m/s, t = 4 s

Now let's plug all the known variables in:

a = (32-20)/4 = 12/4

a = 3 m/s^2

d = (v1)*t + (a*t^2)/2

Let's keep track of all the variables we know:

v1 = 20 m/s, t = 4 s, a = 3 m/s^2

Answer:

This is because of friction and heat lost.

Explanation:

The wavelength of this wave is 1 meter (option d).

To determine the wavelength of a longitudinal wave, we need to find the distance between two consecutive compressions or rarefactions. In this case, the distance between the center of the fifth compression and the center of the ninth compression is given as 4 meters. Since there are four compressions between the fifth and ninth compression, the total distance covered by these four compressions is 4 meters. Therefore, the average distance between consecutive compressions is 4 meters divided by 4, which is 1 meter. The wavelength of a longitudinal wave is the distance between two consecutive points with the same phase, which, in this case, is the distance between consecutive compressions. It is important to note that the number of compressions or rarefactions does not directly affect the wavelength. The wavelength is determined by the distance between consecutive points with the same phase. In this case, the given information allows us to calculate the average distance between consecutive compressions, giving us the wavelength of the wave. (option d).

We can use the following data to get the values of acceleration and the distance covered at top speed:

Maximum speed is 20 m/s (v_max).

Time (t) = 21 seconds

(d) = 270 m is the total distance travelled.

Find the acceleration (A) first:

Applying the equation v = u + at

where an is the acceleration, t is the elapsed time, u is the beginning velocity, and v is the end velocity.

Given: The bus will begin at rest with an initial velocity of 0 metres per second (u).

The formula can be rearranged as follows:

a = (v - u) / t

a = (20 m/s - 0 m/s) / 21 seconds

0.952 m/s2 a = 20 m/s / 21 sec

Therefore, the acceleration of the bus is approximately 0.952 m/s².

Next, let's find the distance traveled at maximum speed (B):

Since the bus starts from rest, it takes time to accelerate to its maximum speed and then decelerate to stop. The distance traveled at maximum speed can be found by subtracting the distances covered during acceleration and deceleration from the total distance.

Distance during acceleration = (1/2) * a * t^2

Distance during deceleration = (1/2) * a * t^2

Distance traveled at maximum speed = Total distance - (Distance during acceleration + Distance during deceleration)

B = d - (0.5 * a * t^2 + 0.5 * a * t^2)

B = 270 m - (0.5 * 0.952 m/s² * (21 sec)^2 + 0.5 * 0.952 m/s² * (21 sec)^2)

B = 270 m - (0.952 m/s² * (21 sec)^2)

B = 270 m - 220.392 m

B ≈ 49.608 m

Therefore, the distance traveled at maximum speed is approximately 49.608 m

Time taken by the car to reach the water below the cliff, time of flight is 3.03 s.

Projectile is an object thrown into the space and which is moving under  the effect of gravity alone near the surface of earth.

Here,

The car is driven over the edge and so it is having a projectile motion from the top of the cliff to the water. The time taken by the car to reach and hit the sea in the projectile motion is called time of flight. When the car just leaves the edge of the cliff, it tends to rest. So the initial velocity is 0.

The height of the cliff, s = 45 m

Using the equation of motion,

s = ut +1/2 at²

45 = 0 + 1/2 x 9.8 x t²

t² = (2x 45)/9.8 = 9.183

Therefore, time of flight,

t = 3.03 s

Hence,

Time taken by the car to reach the water below the cliff, time of flight is 3.03 s.
