Answer:
The value is 
Explanation:
From the question we are told that
The height of the top meter stick above the ground is 
The time taken for the acorn to pass the length of the stick is 
Generally the height of the acorn at the point it is the same height with the metered stick is mathematically represented as
Here 
is height of the meter stick and the value is 1 m (This because we are told in the question that the stick is 1 meter in length ( a meter stick))
So
=> 
Generally the velocity of the acorn just before passing the top of the meter stick is mathematically represented by a kinematic equation as
here u is zero since the acorn started from rest
So
Generally the height of the acorn is

Answer:
(a) R = 1Ω
(b) τ = 3
Explanation:
The time constants of the given circuits are as follows
If the two circuits have equal time constants, then
Therefore, the time constant in any of the circuits is
Answer:
Wow that is tough. Go hide lol
Answer: 3,383.5 kg
Explanation:
from the question we were given the following
tension (T) = 4.5 x 10^4 N
maximum acceleration (a) = 3.5 m/s^2
acceleration due to gravity (g) = 9.8 m/s^2 ( it's a constant value )
mass of the car and its contents (m) = ?
we can get the mass of the car and it's contents from the formula for tension which is T = ma + mg
T = m (a + g)
therefore m = T / (a+g)
m = (4.5 x 10^4 / ( 3.5 + 9.8 )
m = 3,383.5 kg
