Did you try googling it lol thats what i do if its a problem like that. sometimes there are websites that answer it you just have to look really hard
Yes,it's true ok? So how have you been doing
Anything that's moving in a straight line at a constant speed has zero acceleration, and that tells us that there is zero net force acting on it.
Answer:
(a) Force and Pressure
Explanation:
Acc to the formula,
Force = Pressure/Area
Therefore it depends on force and pressure
Answer:
The angular diameter is 77.35 arc-seconds.
Explanation:
The angular diameter, as shown in the figure, is the angle subtended by the the diameter of the object.
Before we do the calculation, we first convert everything to meters.
The diameter of the of the object in meters is
75cm =0.75m,
and the distance to the object in meters is
2 km = 2000 m.
Now, from trigonometry we get:
and since 1 degree = 3600 arc-seconds, in arc-seconds is
