A 70 kg student now sits in the chair and the same 35 N force is applied to the chair. What is the chair's new acceleration?
amid [387]

Answer:

0.5 m/s²

Explanation:

Applying,

F = ma............... Equation 1

Where F = Force applied to the chair, m = mass of the student, a = acceleration of the chair

make a the subject of the equation

a = F/m............ Equation 2

From the question,

Given: F = 35 N, m = 70 kg

Substitute these values into equation 2

a = 35/70

a = 0.5 m/s²

Hence the new acceleration of the chair is 0.5 m/s²

Calculate the work function that requires a 475 nm photon to eject an electron of 1.25 eV.
lapo4ka [179]
The work function has the formula
E = h v

where
E is the energy
h is the constant
v is the frequency

Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
<span>λ is the wavelength
</span>
So.
E = h c / <span>λ
h = E</span><span>λ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15

The work function is:
E = 1.9792 x 10-15 v

All of the following statements about the pyramid of biomass are correct EXCEPT: a. Biomass is the total dry mass of the organis
Goshia [24]

Answer: The answer is option B

Explanation:

The base of the pyramid represents primary producers since they help to pass on energy to consumers as we go higher in the pyramid. They are not consumers because they supply energy and do not use up energy. They are called autotrophs.

An airplane is traveling due east with a velocity of 7.5 × 102 kilometers/hour. There is a tailwind of 30 kilometers/hour. What
Delvig [45]
A tailwind means you add thed velocity of the tailwind to the velovity of the plane (no need for any vectors etc. so you just need (7.5x 102 ) +30 then convert it so it like one of the answers (btw - none of the answers is exactly correct - you need to round to get it) thats what you need to do to get the question
