Answer:
The product of the two numbers is 2.33* 10^13
Explanation:
Given
4.31x10⁷ and 5.41x10⁵
Required
Multiply
The multiplication of the two digits is represented as thus:
This can also be rewritten as
Multiply 4.31 and 5.41
Apply laws of indices
The scientific notation is always in the form: 
Where 
So:
23.3171 can be rewritten as 2.33171 * 10
So, we have:
Also, apply law of indices again
It's always advisable (but not compulsory to approximate to 1 or 2 decimal places)
So:
<em>Hence; the product of the two numbers is 2.33* 10^13</em>
Answer:
Explanation:
We will use the equation F - f = ma, which is just a fancy way of stating Newton's 2nd Law. For us:
F = 5.20 to the right (+)
f = 3.29 to the left (-)
m = 1.05 kg. Therefore,
5.20 - 3.29 = 1.05a and
1.91 = 1.05a so
a = 1.82 m/s/s to the right
Electric energy into light energy and sound energy
So we want to know what changes inside the multimeter when we change the voltage range from 200 V to 20 V, by what factor and does it increase or decrease. What we want when trying to measure the voltage with a multimeter is that a minimal current passes trough the mulitmeter so when we change the voltage range, we decrease the resistance by a factor of 10 because the voltage is decreased by a factor of 10.
If a car crashes into another car like this, the wreck should go nowhere. Besides this being an unrealistic question, the physics of it would look like this:
Momentum before and after the collision is conserved.
Momentum before the collision:
p = m * v = 50000kg * 24m/s + 55000kg * 0m/s = 50000kg * 24m/s
Momentum after the collision:
p = m * v = (50000kg + 55000kg) * v
Setting both momenta equal:
50000kg * 24m/s = (50000kg + 55000kg) * v
Solving for the velocity v:
v = 50000kg * 24m/s/(50000kg + 55000kg) = 11,43m/s
