Answer:

Explanation:
The electric force exerted on the electron is given by:

where
is the magnitude of the electron charge
E = 40000 V/m is the electric field
Substituting,

By comparison, the gravitational force exerted on the electron is:

where
is the mass of the electron
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting,

Answer:
32.5 ms⁻¹
Explanation:
<em><u>Theory
</u></em>
<u>
The law of conservation of linear momentum
</u>
The sum of linear momentum of a system under no external force remains constant.
In this scenario although different forces act on two vehicles by each other when we consider the total system of two cars no external unbalance force act on them. So we can apply this law.
As law says,
The sum of linear momentum before collision = The sum of linear momentum after collision.
Momentum = mass × velocity
1000×40+3000×35 = 1000×v + 3000×37.5
where v = velocity of the red car after the cash
v = 32.5 ms⁻¹
Answer:
Yes, the value will be the same.
Explanation:
Yes, or at least to some degree, that value of K will remain the same. You're looking for a difference in absorbance, and the difference should be visible at all wavelengths, not only at the limit. That being said, resolution varies, and if we don't read the value to the maximum, we can get a less accurate reading.
