Answer: 800 km/h
Explanation:
Use equation for average speed
V=S/t
where S is distance
t is time
S=4800Km
t=6h
---------
V=S/t
V=4800Km/6h=800 Km/h
Answer:
(A) Time period T = 6.28 SEC
(B) At highest point fore is - 575.83 N
(B) At lowest point force is 1050.97 N
Explanation:
We have given that mass m = 83 kg
Radius r = 13 m
Speed v = 6.10 m/sec
(A) Time period of the motion is given by
(b) Net force is given by
Force due to gravity
At highest point
(B) At lowest point
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:
The mass of water is
Explanation:
Given that,
Area of town = 29 km²
Time = 30 min
Height = 2.4 inch
Mass = 103 kg
We know that,
1 m = 39.37 inch
So,
We need to calculate the volume
Using formula of volume
Put the value into the formula
We need to calculate the mass of water
Using formula of density
Put the value into the formula
Hence, The mass of water is
