<h2>
The acceleration of gravity at the location is 9.64 m/s²</h2>
Explanation:
Length of pendulum = 2.5 m
Time taken for 5 swings = 16 seconds
Time taken for 1 swing = 3.2 seconds
Period of pendulum = 3.2 seconds.
We have equation for period of simple pendulum as
Where l is the length of pendulum and g is acceleration due to gravity.
Substituting
The acceleration of gravity at the location is 9.64 m/s²
Answer:
K = 3.1 8 × 10⁴ Nm
Explanation:
Given:
m = 68 Kg
x= 2.1 × 10 ⁻² m (in (2.1×10−2 mm) i think m is repeated just like kgkg in the start of question)
g=9.81 m/s²
K= ?
According to Hooke's Law
F = K x
also F=mg
⇒ mg = Kx
⇒ K = mg/x
K= 68 Kg × 9.81 m/s² / 2.1 × 10 ⁻² m
K = 3.1 8 × 10⁴ Nm

yes, because you dont want to be mean and make her feel worse about it and hiv has something do with s3x not germs so yes go
Explanation:
Given:
u = 7.00m/s, the initial vertical velocity of the package.
Assume that g = 9.8 m/s².
Neglect air resistance.
All quantities are measured as positive upwards.
The height from which the package is dropped is 155 m above ground.
Let t = the time for the package to hit the ground.
Therefore
(7.00 m/s)*(t s) - (1/2)*(9.8 m/s²)*(t s)² = (- 155 m)
4.9t² - 7t - 155 = 0
or
t² - 1.4286t - 31.6327 0
Solve with the quadratic formula.
t = (1/2)*[1.4286 +/- √(2.0409 + 126.5308)]
= 6.384 s or - 4.955 s
Reject negative time.
Answer: 6.384 s
Answer:
Analysis
Explanation:
Because you must Analysis each and every cold too find out which virus caused this.
It’s weird because Interpretation and Analysis have the meaning of examination
