You have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. If the house circuit provides

marusya05 [52]

Answer:

I = 0.029 A

Explanation:

It is given that,

Power of hallway is 3.5 watts

The house circuit provides 120 volts

We need to find the current through this bulb. The power of electric bulb is given by :

$P=VI$

$I=\dfrac{P}{V}\\\\I=\dfrac{3.5}{120}\\\\I=0.029\ A$

So, the electric current is 0.029 A.

A ping pong ball has a mass of about 2.45 grams. Suppose that Forrest Gump hits the ball across the table with a speed of about

KonstantinChe [14]

Answer:

0.0196 Joules

Explanation:

Kinetic energy is half the product of mass and velocity squared.

K.E=0.5 m*v^2; The m is the mass in kilograms and v is the velocity in meters per second.

We will convert grams to kilograms:

2.45 grams = 0.00245 kilograms.

Calculating kinetic energy:

mass:0.00245 kg

velocity:4 m/s

K.E = 0.5 *0.00245*4^2 = 0.0196 Joules.

P14.003A spherical gas-storage tank with an inside diameter of 8.1 m is being constructed to store gas under an internal pressur

Artist 52 [7]

Answer:

The minimum wall thickness required for the spherical tank is 0.0189 m

Explanation:

Given data:

d = inside diameter = 8.1 m

P = internal pressure = 1.26 MPa

σ = 270 MPa

factor of safety = 2

Question: Determine the minimum wall thickness required for the spherical tank, tmin = ?

The allow factor of safety:

$\sigma _{a} =\frac{\sigma }{factor-of-safety} =\frac{270}{2} =135MPa$

The minimun wall thickness:

$t=\frac{Pd}{4\sigma _{a} } =\frac{1.26*8.1}{4*135} =0.0189m$
