Ohms Law: V = IR

V is the voltage in volts

I is the current in amps

R is the resistance in Ohms

Rearrange: R = V/I

R = (110)/(0.050)

R = 2200

There are 2200 Ohms of resistance in the circuit.

A magnet is made from materials that is magnetized and create its own persistent magnetic field while a electromagnet is mad from coil of wire which acts as a magnet when electric current passes through it.

Illusion [34]

Complete Question

Apollo 14 astronaut Alan B. Shepard Jr. used an improvised six-iron to strike two golf balls while on the Fra Mauro region of the moon’s surface, making what some consider the longest golf drive in history. Assume one of the golf balls was struck with initial velocity v0 = 32.75 m/s at an angle θ = 32° above the horizontal. The gravitational acceleration on the moon’s surface is approximately 1/6 that on the earth’s surface. Use a Cartesian coordinate system with the origin at the ball's initial position.

Randomized Variables

vo 32.75 m/s

theta 32 degrees

What horizontal distance, R in meters, did this golf ball travel before returning to the lunar surface?

Answer:

The  horizontal distance is  R =  590.2 \ m  

Explanation:

From the question we are told that

 The initial  velocity is  v_o =  32.75 \  m/s

  The angle is  \theta =  26^o

  The gravitational acceleration of the moon is g_m  =  \frac{1}{6}  *  9.8   = 1.633 m/s^2

 Generally the distance traveled is mathematically represented as

    R =  \frac{v_o^2 sin 2(\theta)}{g_m}

=> R =  \frac{32.75^2 sin 2(32)}{1.633}

=> R =  590.2 \ m

Calculate the heat flux (in W/m2) through a sheet of a metal 11-mm thick if the temperatures at the two faces are 350 and 110 ˚C
Masja [62]

q = 1156363.6W/m².

To calculate the heat flux per unit area (W/m²) of a sheet made of metal:

q = -k(ΔT/Δx)

q = -k[(T₂ - T₁)/Δx]

Where, k is the thermal conductivity of the metal, ΔT is the temperature difference and Δx is the thick.

With Δx = 11 mm = 11x10⁻³m, T₂ = 350°C and T₁ = 110°C, and k = 53.0 W/m-K:

q = -53.0W/m-K[(110°C - 350°C)/11x10⁻³m

q = 1156363.6W/m²
