Answer:
a = 64 ft / s²
Explanation:
The force in a spring is given by Hooke's law
F = -k x
Let's use the initial data to calculate the spring constant
k = F / x
Reduscate to the English system
x = 3 in (1foot/12 in) =0.25 foot
k = 0.3 / 0.25
k = 1.2 lb / foot
Now we can use Newton's second law
F = ma
a = F / m
a = -k x / m
m = w / g
m = 0.3 / 32 = 0.009375
x= 6 in (1foot /12 in)= 0.5 foot
a = - 1.2 0.5 / 0.009375
a = 64 ft / s²
In the electromagnetic spectrum, "Blue" is the "highest" <span>frequency color of visible light.
Or I</span>n the electromagnetic spectrum, "Red" is the "Lowest" frequency color of visible light.
Hope this helps!

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:
Explanation:
If we assume the balloon to be a constant pressure device and the gas filling it to be ideal.
pV = nRT
p, n and R are all constants so
V is directly proportional to T (which must be in Kelvins)
1.8/1.5 = (T + 273)/(25 + 273)
T = 84.6
T = 85°C
