Answer:
Answer is = 12.3 x 10^6 N
Explanation:
We need to calculate force on the charge which is in Newtons:
Formula is = K q1q2/r^2
k is constant depeneds on the permitivity of the medium and its value is 9x10^9 Nm^2/C^2
q1 and q2 are charges and r is the distance between these two charges so just by putting values we get F= 9x10^9 x 1.1x10^-6/(8x10^-2)^2 (we get the above answer in newton)
You can use the formula A=F/M, the rate that it is being accelerated upward is 3.3, so about 3.
The mass of the basket = weight/acceleration due to gravity. (75/10=7.5 kg)
100 (upward force from girl) minus 75 (downward force from basket) is 25.
So 25=7.5a, which becomes 25/7.5, which equals 3.33 kg x m/s.
And when rounded, the momentum is about 3, (or 3 p).
Hope this helps!
Answer:
acceleration is 1.59 m/s²
required % is 16.22 %
Explanation:
given data
radius = 63 m
speed = 10 m/s
to find out
acceleration of the car and acceleration due to gravity
solution
we know car is moving in circular path
so acceleration will be, a = 
.........1
put here value
a = 
a = 1.59 m/s²
so acceleration is 1.59 m/s²
so acceleration due to gravity as a percentage is 9.8 m/s²
required % = 
required % = 16.22 %
Explanation:
Carbon-14 is normally used to date living organisms (all living things we know today contain mostly carbon). It can be used for samples up to about 60000 years old. Carbon-12 is the non-radioactive form that we encounter daily. Relative dating determines dates relative to each other, such as ordering of period or events.
Uranium 235 dating can determine date samples a million years old and up, so is more suited for rocks.
