Introducing vehicles that are built with lighter equipment, better gearing, improved aerodynamics, and better development in driving skills.
(25m north) + (10m south) = 15m north
(10m east) + (5m west) = 5m east
So the bee is now 15m north and 5m east of the hive.
Answer:
frequency = 1475.45 Hz
Explanation:
given data
frequency f1 = 1215 Hz,
frequency f2 = 1265 Hz
police car moving vp = 25.0 m/s
solution
speed of sound u = 343 m / s
speed of the other car = v
when the police car is stationary
the frequency the other car receives is
f2 = f1 × ................1
and
the frequency the police car receives is
f2 = f1 × ..................2
now from equation 1 and 2
v = 4.77 m/s
and
frequency the other car receives is
f2 = f1 × ......................3
and
the frequency the police car receives is
f2 = f1 × .......................4
now we get
f2 = f1 ×
f2 =
f2 = 1475.45 Hz
Answer:
Explanation:
Given
mass
Force
door knob is located at a distance of r=0.8 m from axis
Angular acceleration of door
Torque
where I=moment of inertia
Answer:
1 m/s
Explanation:
Impulse = Change in momentum
Force × Time = Mass(Final velocity) - Mass(Initial Velocity)
(1.0)(1.0) = (1.0)(Final Velocity) - (1.0)(0)
Final velocity = <u>1 m/s</u>
