Answer:
a. 1 Newton = 100000 Dyne
b. a represents acceleration.
Explanation:
Newton is the standard unit (S.I) of measurement of force. Converting 1 Newton to dyne we have;
1 Newton = 10⁵ Dyne
1 Newton = 100000 Dyne
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Hence, we can deduce that a represents the acceleration of an object and it's measured in meters per seconds square.
I truly believe so, that’s a definite yes
when two vectors are inclined at some angle to each other then the magnitude of resultant of two vectors is given as
here A and B are the magnitude of two vectors and theta is the angle between them
now here we know that two vectors are of magnitude 0.25 m/s^2 each and they are inclined at angle of 45 degree
now we will plug in all data above
A = B = 0.25
So the magnitude of resultant acceleration will be 0.46 m/s^2
(1×10^-5)/(1.6×10^-19)= 6.25×10^13 electrons(ans)
Notice that the charge of a sphere is very larger than charge of electron obviously, so each electron on the sphere is made of 1.6×10^-19 charge, so you found how many of these charges are required for you to make a charge of 1×10^-5
for Example: your electron has charge 2 on it
and the sphere has charge 200 on it, then the number of electrons that make up that charge will be
200/2 = 100 electrons.
Answer:35.2 ft
Explanation:
Given
height of stick =4 ft
shadow length =2.8 ft
Angle of elevation of sun is
let the height of tree be h
as will remain same thus
h=35.2 ft
