A student is playing with a radio-controlled race car on the balcony of a sixth-floor apartment. An accidental
pentagon [3]

Answer:

No, it is independent

Explanation:

As we know that car is moving horizontally

so the vertical component of the speed is zero initially

so in order to hit the ground we know that

\Delta y = v_y t + \frac{1}{2}at^2

so here we know that

h = 0 + \frac{1}{2}gt^2

on solving above equation for time

t = \sqrt{\frac{2h}{g}}

so we will say that it will not depends on the initial horizontal speed

As the wavelength increases, the frequency (2 points) decreases and energy decreases. increases and energy increases. decreases
frozen [14]
Bohr's equation for the change in energy is
\Delta E= \frac{hc}{\lambda}
where
h = Planck's constant
c == the velocity of light
λ = wavelength.

The velocity is related to wavelength and frequency, f, by
c = fλ

Let us examine the given answers on the basis of the given equations.

a. As λ increases, f decreases and ΔE decreases.
     TRUE

b. As λ increases, f increases and ΔE increases.
    FALSE

c. As λ increases, f increases and ΔE decreases.
    FALSE

Answer: 
As the wavelength increases, the frequency decreases and energy decreases.

According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?
Aliun [14]
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

A certain spring stretches 15 cm when a load of 50.0 N is suspended from it. How much will the spring stretch if 78N is suspende
andriy [413]

Answer:

23.4 cm

Explanation:

15 : 50 = x : 78

15*78 = 50x

x = 15*78/50 = 23.4 cm
