just swim In water and find your shoe
Answer:
Option (D) is correct.
Explanation:
The balloon lands horizontally at a distance of 420 m from a point where it as released.
Velocity of air balloon along +X axis =10 m/s
velocity of ball=4 m/s along + X axis
the velocity of balloon gets added to the velocity of ball. So the resultant velocity of the balloon=10+4 = 14 m/s
time taken= 30 s
The distance traveled is given by d= v t
d= 14 (30)
d= 420 m
Thus the balloon lands horizontally at a distance of 420 m from a point where it as released.
It is called polarizability. A dipole moment is needed for the molecule or atom due to the distortion of the electron cloud. A dipole is a pair of electrical charges that have opposite signs and during a dipole moment two charges separate.
Answer: Objective Observations
Explanation: The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false
Explanation:
Given that,
Height = 3.40 m
Speed of water = 9.32 m/s
Angle = 80.0°
Suppose the angle at diving board is 10°.
(a). We need to calculate the magnitude of his initial velocity
Using the formula of horizontal velocity
Put the value into the formula
(b). We need to calculate the direction of his initial velocity,
The direction of his initial velocity is 10° east of south.
(c). We need to calculate the time
Using formula of time
Put the value into the formula
We need to calculate his maximum height above the water
Using equation of motion
Put the value into the formula
Hence, This is the required solution.
