The number converted is
Explanation:
In order to convert from the original units to the final units, we have to keep in mind the following conversion factors:
The original unit that we have is
Therefore, it can be rewritten as:
Therefore, since the initial number was 0.779, the final value is

Answer:
distance travelled= 12 x 3=36 m
Explanation:
It is given that,
Initial speed of a golfer, u = 29 m/s
If it travels the maximum possible distance before landing. It means that it is projected at an angle of 45 degrees.
(a) We need to find the time spent by the ball in the air. It can be calculated by using second equation of motion.
Here,
a = -g
s = 0 (it is displacement and it is equal to 0 as the ball lands on the green).
So,
So, it will take 4.184 seconds in the air.
(b) let x is the longest hole in one that the golfer can make if the ball does not roll when it hits the green. It can be given by :
Hence, this is the required solution.
Explanation:
Mercury is the closest planet to the sum, but its mean temperature is only 67°C. This is because Mercury has almost no atmosphere to hold in heat and keep the surface warm.

Answer:
V₂ = 2 L
Explanation:
given,
P₁ = 203 kPa
V₁ = 0.5 L
Now, volume is expanded
P₂ = 50.8 kPa
V₂ = ?
Using Boyle's law
P₁V₁ = P₂ V₂
inserting all the values
V₂ = 2 L
Hence, new volume of air in the pump is equal to 2 L.
