What is the mass of a baseball clocked moving at a speed of 105 mph or 46.9 m/s and wavelength 9.74 × 10-35m?
Andrew [12]
For this problem to be solved, we make use of the de Broglie formula which is written below as follows:

λ = h/mv
where h is 6.626×10⁻³⁴ J·s

9.74 × 10⁻³⁵ m = 6.626×10⁻³⁴ J·s/ (m)(46.9 m/s)
Solving for m,
<em>m = 0.145kg</em>

A bullet is fired horizontally from a handgun at a target 100.0 m away. If the initial speed of the bullet as it leaves the gun
Lera25 [3.4K]

Answer:

The distance is 0.53 m.

Explanation:

Given that,

Target distance = 100.0 m

Speed of bullet = 300 m/s

We need to calculate the total time

Using formula of time

t=\dfrac{d}{v}

Put the value into the formula

t=\dfrac{100.0}{300}

t=0.33\ sec

Now, consider vertical motion of bullet.

Initial velocity of bullet in vertical direction = 0 m/s

We need to calculate the vertically distance

Using equation of motion

s=ut+\dfrac{1}{2}gt^2

Put the value in the equation

s=0+\dfrac{1}{2}\times9.8\times(0.33)^2

s=0.53\ m

Hence, The distance is 0.53 m.

Sound travels slower in colder air than it does in warmer air. Make a claim about the effect of air temperature on the speed of
vladimir1956 [14]

Answer: The temperature of the air affects the speed of sound in the due to the fact that colder contains air molecules with low kinetic energy. For warm air the kinetic energy of the molecules is high causing them to move in rapid motion. Because of these vibrations and collisions sound waves moves in a faster rate.
