Looking at the wave diagram which best describes the wave

What happens to a decimal place in the number when you are converting from a smaller metric unit to a larger unit?

I dont have any idea :P

One gram of Uranium averages release 1.01 KJ (10^7) of energy. How much mass could be converted to energy to release this much e

frutty [35]

Answer:

The amount of mass that needs to be converted to release that amount of energy is $1.122 X 10^{-7} kg$

Explanation:

From Albert Einstein's Energy equation, we can understand that mass can get converted to energy, using the formula

$E= \Delta mc^{2}$

where $\Delta m$ = change in mass

c = speed of light = $3 \times 10 ^{8}m/s$

Making m the subject of the formula, we can find the change in mass to be

$\Delta m = \frac{E}{c^{2}}= \frac{1.01 \times 10^{3} \times 10^{7}}{(3 \times 10^{8})^{2}}= 1.122 \times 10 ^{-7}kg$

There fore, the amount of mass that needs to be converted to release that amount of energy is 1.122 X 10 ^-7 kg

2) What must be connected for an electrical current to flow in a simple current?

d.moving magnets,conductors, load to do work

here moving magnets will work as generator and conductors is used as connectors.

5)What is the purpose of a load in a circuit?

c.provide resistance to keep the voltage strong

Load will provide the resistance to the circuit and help to build the voltage across it

6) What cause an electric current from a generator

d.Magnets and conducting wires move near each other

here when magnets move near wires then it will induce the electric current and behaves like generators

7) What do all generators have in common

b.they transform mechanical into electrical energy

They have magnets and rotating coils which will convert magnetic energy to electrical energy

8) How can we measure electrical current

b.the pressure force is voltage;the # of electrons moving is amperes

this voltage and number of electrons will help to calculate current

It requires a force of 100 N to stretch a spring of negligible mass by a distance of 0.1 m. If the spring instead stretches a di

Mariana [72]

by the formula of spring force we know that

$F = kx$

here we know that

$F = 100 N$

$x = 0.1 m$

now we will have

$100 = k \times 0.1$

$k = 1000 N/m$

now by similar way if the stretch in spring is 0.25 m

force is given by

$F = kx$

$F = 1000 \times 0.25$

$F = 250 N$

so it will require F = 250 N force

Saturn’s moon titan has a mass of 1.35 × 10^23 kg. if titan is 1.19 × 10^6 km from saturn, and saturn’s mass is 5.86 × 1026 kg,

prohojiy [21]

Answer:The gravitational force equation is Fg=(G*M*m)/r² where, G is the gravitational constant, G=6.67*10^-11 m³/kg*s², M is the mass of Saturn, M=5.86*10^26, m is the mass of Titan, m=1.35*10^23 and r is the distance, r=1.19*10^6 km=1.19*10^9 m. Now we simply input the numbers into the equation:

Fg=(6.67*10^-11)*(5.86*10^26)*(1.35*10^23)/(1.19*10^6)²

Fg=(5.277*10^39)/(1.41*10^18)=3.743*10^21 N

The correct answer is the third one.
