Answer:
Our estimate not done correctly because the width was unrealistic.
Explanation:
Given that,
Length = 6 m
Width = 0.5 m
We need to calculate the area of rectangular floor
Using formula of area
Where, l = length
w= width
Put the value into the formula
We need to find why this estimate not done correct
Using given data
We can say that,
We assume width was unrealistic.
The length of room is 6 m.
We know that,
So, the length would be 20 feet.
The width of room is 0.5 m.
The width of room would be 1.64 feet.
So, the area will be
Hence, Our estimate not done correctly because the width was unrealistic.
Given : A car starts from rest and retains the acceleration of 4m/s² in 20 second. Calculate its final velocity.
Solution : As we know that a car starts from rest so it's initial velocity should be 0 m/s. Acceleration is 4 m/s² and time taken is 20 sec. So, we need to calculate it's final velocity which we can get it usi g the first equation of motion.
First Equation of Motion : v = u + at
Putting all the required values in the formula we will get v
<u>Henceforth, final velocity is 80 m/sec.</u>
Answer:
1.4 billion light years away
Explanation:
v = Recessional velocity = 30000 km/s[/tex]
= Hubble constant =
D = Distance to the galaxy
According to Hubble's law
The galaxy is 1.4 billion light years away
Iduction uses magnets to create heat, conduction requires more electricity to creat heat.
