A rock is dropped from a sea cliff and hits the water 3.2s later. How high is the cliff? How long would it take sound to travel

Kruka [31]

A rock is dropped from a sea cliff and hits the water 3.2s later. How high is the cliff?

t = sqrt(2y/g)
3.2 = sqrt(2y/9.81)
y = 50.23 m

How long would it take sound to travel the same distance?
t = 50.23 / 343 m/s
t = 0.15 s

How long would it take light to travel this distance?
t = 50.23 / 299 792 458 m / s
t = 1.68x10^-7 s

The magnetic field at the center of a 1.0-cm-diameter loop is 2.5 mT.

olga nikolaevna [1]

Answer:

(a) The current in the wire is 19.89 A

(b) The distance from the wire is 0.159 cm

Explanation:

Given;

magnetic field, B = 2.5 mT

diameter of the wire, d = 1 cm

radius of the wire, r = 0.5 cm = 0.005 m

(a) The current in the wire is calculated as;

$I = \frac{2Br}{\mu_0} \\\\I = \frac{2\times 2.5 \times 10^{-3} \times 0.005 }{4\pi \times 10^{-7} } \\\\I = 19.89 \ A$

(b) The distance from the wire where the magnetic field is 2.5 mT is calculated as;

$B = \frac{\mu_0 I}{2\pi d} \\\\where;\\\\d \ is \ the \ distance \ from \ the \ wire\\\\d = \frac{\mu_0 I}{2\pi B} = \frac{4 \pi \times 10^{-7} \times 19.89}{2\pi \times 2.5 \times 10^{-3}} = 0.00159 \ m = 0.159 \ cm$

Sonbull [250]

Answer:

Force, F = 124 N

Explanation:

We have,

Mass of bicycle is 12 kg and mass of rider is 50 kg

Total mass of the system is 12 kg + 50 kg = 62 kg

Acceleration of the system is 2 m/s²

It is required to find the force required to accelerate the system. The force acting on an object is given by :

$F=ma\\\\F=62\ kg\times 2\ m/s^2\\\\F=124\ N$

So, the force of 124 N is acting on the system.

If a ski lift raises 150 passengers averaging 590 N in weight to a height of 244 m in 96.3 s, at constant speed, what average po

SVEN [57.7K]

Answer:

224236.76 W

Explanation:

Power: This can be defined as the rate of change of energy. The S.I unit of power is Watt(W).

From the question,

P = E/t ......................... Equation 1

Where P = power, E = Energy or work, t = time.

But,

E = Wt×d.................. Equation 2

Where Wt = Total weight of the passengers, d = distance.

Substitute equation 2 into equation 1

P = (Wt×d)/t.............. Equation 3

Given: Wt = 590×150 =88500 N, d = 244 m, t = 96.3 s.

Substitute into equation 3

P = (88500×244)/96.3

P = 224236.76 W
