Answer:

Technician A is right.                                                    

Explanation:

Given that,

Voltage of circuit, V = 12 volt

Current in the circuit, I = 3 A

Technician A says the electric power in this circuit is 36 watts. Technician B says the electric power in this circuit is 4 watts. We need to say that which technician is correct.

The power of any circuit is given by :

P=V\times I

P=12\ V\times 3\ A

P = 36 watts

So, technician A is right. Hence, this is the required solution.

A person with a mass of 72 kg is riding a bicycle is accelerating at a rate of 5m/s on a horizontal surface. What is the weight
nikklg [1K]

Answer:

w = 706.32 [N]

Explanation:

The force due to gravitational acceleration can be calculated by means of the product of mass by gravitational acceleration.

w = m*g

where:

w = weight [N] (units of Newtons)

m = mass = 72 [kg]

g = gravity acceleration = 9.81 [m/s²]

Then we have:

w = 72*9.81\\w = 706.32 [N]

If an equation is demensionally correct does this mean that the equation is true
DerKrebs [107]

Explanation:

If an equation is dimensionally correct, it does not mean that the equation must be true. On the other hand, when the equation is dimensionally correct, the equation cannot be true. Dimensional analysis is a technique used to check whether a relationship is correct

A 12.0 kg object is attached to a cord that is wrapped around a wheel of radius 10.0 cm. the acceleration of the object down the
olganol [36]

 a) We use the formula:

T = [g sinθ – a] * m

where g is gravity, θ is the angle, a is acceleration, m is mass

T = [9.81 sin37 - 2.00] * 12 = 46.85 N <span>

b) We use the formula for moment of interia:</span>

I = T * r² / a

I = 46.85 * 0.10² / 2.00 = .2343 kg∙m² <span>

c) The formula we can use here is:</span>

w = α * t = (a/r) * t

w = (2/.10) * 2

<span>w = 40 rad/sec</span>

While ice skating, you unintentionally crash into a person. Your mass is 60kg
miss Akunina [59]

Answer:

The speed is 6.1m/s with an angle of 56.3 degrees north of east.

Explanation:

We meed to apply the Linear momentum theorem:

m1*vo1+m2*vo2=m1*vf1+m2*vf2\\60*(8.0m/s(East))+80*(9.0m/s(North))=140*vf\\vf=3.4m/s(East)+5.1m/s(North)

The magnitude of the velocity is given by:

v=\sqrt{Veast^2+Vnorth^2} \\v=6.1m/s

and the angle:

\alpha =arctg(\frac{Vnorth}{Veast})\\\alpha=56.3^o
