Answer:
The appropriate solution is "61.37 s".
Explanation:
The given values are:
Boat moves,
= 10 m/s
Water flowing,
= 1.50 m/s
Displacement,
d = 300 m
Now,
The boat is travelling,
=
=
Travelling such distance for 300 m will be:
⇒
On putting the values, we get
Throughout the opposite direction, when the boat seems to be travelling then,
=
=
Travelling such distance for 300 m will be:
⇒
On putting the values, we get
hence,
The time taken by the boat will be:
=
=
Answer:
The magnitude of the electric force on a protein with this charge is
Explanation:
Given that,
Electric field = 1500 N/C
Charge = 30 e
We need to calculate the magnitude of the electric force on a protein with this charge
Using formula of electrostatic force
Where, F = force
E = electric field
q = charge
Put the value into the formula
Hence, The magnitude of the electric force on a protein with this charge is
