Answer:
Explanation:
hence making time the subject then
Substituting 50 cm which is equivalent to 0.5 m for distance and velocity as given as 
we obtain
From kinematic equation
and taking g as 9.81 then
Answer:
Explanation:
Charge q will remain inside the given sphere and charge Q will remain outside it.
So charge inside sphere = - 40 x 10⁻¹² C
According to Gauss's law
Net flux over the spherical closed surface
= charge inside the surface / ε₀
= - 40 x 10⁻¹² / 8.85 x 10⁻¹²
= - 4.52 Weber.
- ve sign indicates , flux is oriented towards the center.
If you don't give unit with your magnitude (number) then, anyone can't figure it what you are talking about!
Suppose, you said, the weight of an iron bar is 10.
What does that mean? We can't even figure out how heavier is it.
Now, If you tell that the weight of a person is 10 Newton, then it makes sense 'cause 10 N has specific value. When you wrote 10 then, it could be newton, dyne or any other derived unit.
Hope this helps!
Answer:
1. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time
2. 36÷4= 9
(formula) Speed = distance ÷ time
3. Meter (M) centimeter (cm) kilometers (km)
4. Seconds , Hour, Minute
5. 65÷13=5 (object A)
125÷ 25= 5 (object B)
their both Equal of the amount of speed, so they are travelling at the same speed
