Answer:
The sound level will be 1.870 dB louder.
Explanation:
Given that,
Power = 130 W
Power = 200 W
We need to calculate the sound level
Using formula of sound level
For one amplifier,
...(I)
For other amplifier,
...(II)
For difference in dB levels
Hence, The sound level will be 1.870 dB louder.
Answer:
20 m/s
Explanation:
The vertical component of the velocity of the ball is equal to the length of the perpendicular of a triangle such that it makes an angle of 30 degrees from the base and the length of the hypotenuse is 40 m/s. Sin(∅)*hypotenuse is the length of the perpendicular.
Vertical component of velocity is given by 40Sin(30°)=20
It's a virtual force ... one that seems to be there but isn't really there.
When something tries to fly or flow straight, through a rotating neighborhood, it ends up flying or flowing in a curved path, AS IF there were a force acting on it to make it curve. THAT apparent force is the Coriolis force.
It's what makes air, flowing away from high pressure or into low pressure, form the big rotating pressure systems on the rotating Earth.
Answer:
18 m/s
Explanation:
1.8 meters / 0.1 seconds = 18 m/s
