diamong [38]

Answer:

B. 1.55 × 10³ m/s

Explanation:

f = 3.02 x 10^6 Hz

wavelength = 5.13 x 10^-4 m

v = ?

v = f*lamda

v = 3.02 x 10^6 × 5.13 x 10^-4

v = 1.55 × 10³ m/s

There is a 50 g sample of Ra-229. It has a half-life of 4 minutes.
Sloan [31]

Via half-life equation we have:


A_{final}=A_{initial}(\frac{1}{2})^{\frac{t}{h} }


Where the initial amount is 50 grams, half-life is 4 minutes, and time elapsed is 12 minutes.  By plugging those values in we get:

A_{final}=50(\frac{1}{2})^\frac{12}{4}=50(\frac{1}{2})^{3}=50(\frac{1}{8})=6.25g


There is 6.25 grams left of Ra-229 after 12 minutes.

3. A 65 kg runner exerts a force of 59N. What is the acceleration of the<br> runner?
Mandarinka [93]

Answer:

<h2>1.10 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{65}{59}  \\  = 1.101694...

We have the final answer as

<h3>1.10 m/s²</h3>

Hope this helps you
