Answer:
where L is the length of the ramp
Explanation:
Let L (m) be the length of the ramp, and g = 9.81 m/s2 be the gravitational acceleration acting downward. This g vector can be split into 2 components: parallel and perpendicular to the ramp.
The parallel component would have a magnitude of
We can use the following equation of motion to find out the final velocity of the book after sliding L m:
where v m/s is the final velocity, 
= 0m/s is the initial velocity when it starts from rest, a = 2.87 m/s2 is the acceleration, and 
is the distance traveled:
Momentum of an object is defined as product of mass and velocity
so it is given as
here it is given that
mass = 0.15 kg
momentum = 6 kg m/s
so by plug in values in the above equation
so its speed will be 40 m/s
The periodic table is in increasing atomic mass. Hope this helped.
C should be it. Correct me if im wrong xd
Answer:
Electric field, E = 
Explanation:
Given that,
The potential difference across the membrane, 
The thickness of the membrane is, 
We need to find the magnitude of the electric field in the membrane. We know that the relation between electric field and electric potential is given by :
So, the magnitude of the electric field in the membrane is .
