Answer:

Though no question is specified here but let analyzed experiences of each

Explanation:

1. Required a force to stop it (Law of inertial). Constant acceleration

2. will have reduced acceleration (deceleration)

3. Uniform acceleration may set in. it accelerate

4. maximized it speed since no friction affect it motion

5. accelerating. Vo=0 and V gradually increased

6. less or no friction opposes the motion

7. It experience reduce motion based on air friction

8. constant acceleration due to gravity

9. g can be a bit affected but still about equal

Two identical loudspeakers 2.30 m apart are emitting sound waves into a room where the speed of sound is 340 m/s. Abby is standi

Dimas [21]

Answer:

Abby is standing (4.5^2 + 2.3^2)^1/2 from the far speaker

D2 = 5.05 m from the far speaker

The difference in distances from the speakers is

5.05 - 4.5 = .55 m (Let y be wavelength, lambda)

n y = 4.5

(n + 1) y = 5.05 for the speakers to be in phase at smallest wavelength

y = .55 m subtracting equations

f = v / y = 340 / .55 = 618 / sec should be the smallest frequency

a boat is moving across a lake during a race at a rate of 63m/s^2 and reaches a velocity of 96m/s.how long did it take the boat

Paraphin [41]

Answer:

1.52s

Explanation:

Given parameters:

Acceleration = 63m/s²

Final velocity = 96m/s

Unknown:

Time taken = ?

Solution:

To solve this problem, we use one of the kinematics equation:

v = u + at

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

So;

96 = 0 + 63t

t = 1.52s

A wire with a length of 150 m and a radius of 0.15 mm carries a current with a uniform current density of 2.8 x 10^7A/m^2. The c

Mrac [35]

Answer:

The current is 2.0 A.

(A) is correct option.

Explanation:

Given that,

Length = 150 m

Radius = 0.15 mm

Current density $J=2.8\times10^{7}\ A/m^2$

We need to calculate the current

Using formula of current density

$J = \dfrac{I}{A}$

$I=J\timesA$

Where, J = current density

A = area

I = current

Put the value into the formula

$I=2.8\times10^{7}\times\pi\times(0.15\times10^{-3})^2$

$I=1.97=2.0\ A$

Hence, The current is 2.0 A.

Which of the following is an example of a solution: the atmosphere, milk, an Italian salad dressing, are muddy water

weeeeeb [17]

A milk

Explanation:

A solution is a homogeneous mixture of solutes and solvents. The solute is the substance usually solid dissolved to make the solution.

The solute is usually present in small amount compared to the solvent.
A milk is solution of different components.
Most liquid milk are made up of powdered milk dissolved in water and sugar added to it.
All the constituent will now exist in a single phase as a liquid and be homogeneous.
They are homogeneous in the sense that all the parts are uniform.
