Answer:
5 solar days is 432,000 seconds
Explanation:
One solar day is the time the meridian of the Sun crosses passes through a specified place.
Due to the elliptical orbit of the Earth round the Sun, one average solar day on Earth is equivalent to 24 hours with some days longer and some days shorter each by a few minutes
Therefore, we have;
5 solar days = 5 × 24 hours × 60 minutes/hour × 60 seconds/minute = 432,000 seconds
5 solar days = 432,000 seconds
Answer: 2.61 s
Explanation:
We are given the following data:
is the initial height of the object
is the initial height of the object
In addition, the motion of the object is given by:
(1)
Where:
is the final height of the object
is the time the object is in the air before hitting the ground
Rewritting (1) with the given data:
(2)
Solving the quadratic equation with the quadratic formula 
, where 
, 
, 
and choosing the positive value of time:
(3)
(4) This is the time
The amount of a radioactive element over time can be written as:
So, considering that we know the time of its half life, we know how long it takes to get to half the original amount. This is (usint the amount of days in microseconds):
Thus, lambda=3.82*10^(-11)/microseconds
Answer:
Explanation:
Let F be the force applied by Ricardo
work done by him = force x displacement
= F x 54 unit
output of work
= mgh , m is mass of luggage , h is height by which luggage is lifted .
= 645 x 32 x 4.5
= 92880 ft-poundal.
According to question
output / input = .95
92880 / (F x 54) = .95
F = 1810.52 poundal.
Answer:
186 N
ExplanatioN
Weight is essentially just a measurement of the force of gravity, so you can use this equation.
F = mg
Force = Mass × Acceleration due to Gravity
F = 19kg × 9.8m/s^2. (Acceleration due to Gravity on Earth.)
F = 186.02N
