178 centimeters is exactly, precisely, the same length as ...
-- 0.00178 kilometer
-- 1.78 meters
-- 1,780 millimeters
-- 1,780,000 micrometers
-- 1,780,000,000 nanometers
Verrrrrry interesting !
Acceleration = (change in speed) / (time for the change)
The car's acceleration is (60 mph) / (3.8 sec) = (60/3.8) mile/hr-sec .
Final speed = (original speed) + (acceleration · time)
= (30 mi/hr) + (60/3.8 mi/hr-sec)·(6 sec)
= (30)mi/hr + (360 / 3.8)mi/hr
= 124.7 mph .
Answer:
Explanation:
surface area of furnace = 6 x .6²
=2.16 m²
Rate of heat loss = k A ( θ₂ -θ₁ ) / t where k is coefficient of thermal conductivity , A is surface involved , θ₂ -θ₁ is temperature difference and t is thickness .
For fire clay thermal conductivity
= .05 W / m . K
.05 x 2.16 x ( 630 - 70 ) / .04
= 1512 W
= 1.5 kW .
Answer:
pressure in liquids is given as:
P= hpg
where h is the depth
where p is the density
where g is 10
Explanation:
From the formula above
p = 10 X 1000 X 10
p = 100000N/m
