Answer:
226.2 m/sec
Explanation:
We have given 
The plank's constant 
Mass of electron 
Now according to Heisenberg uncertainty principle 
So
Answer: See below
Explanation:
<u>Given:</u>
Mass of the Mercedes-Benz (m) = 1700 kg
Inclination of the road (θ) = 15.0
<em>The free body diagram is shown in figure attached below</em>

a) The normal force is equal to the cos component of the weight of the car.

b) The static force will be equal to the weight's sin component.

Our planet is closed system because there is a limit of how much matter could be exchanged.
Explanation:
Given that,
Frequency in the string, f = 110 Hz
Tension, T = 602 N
Tension, T' = 564 N
We know that frequency in a string is given by :
, T is the tension in the string
i.e.
, f' is the another frequency


f' =106.47 Hz
We need to find the beat frequency when the hammer strikes the two strings simultaneously. The difference in frequency is called its beat frequency as :



So, the beat frequency when the hammer strikes the two strings simultaneously is 3.53 beats per second.
