Convert .00016 to scientific notation
1 answer:
Answer:
Explanation:
Recall that scientific notation involves expressing the number in powers of ten, and using a multiplicative factor whose value is larger than or equal to 1 (one) and strictly smaller than 10 in the form:
and with n an integer value.
in our case, notice that 0.00016 = 16 / 100000 = 1.6 / 10000
and that denominator can be expressed as: 10^4, and can also be brought to the numerator as a negative power of ten:
1.6 / 10000 = 1.6 / 10^4 = 1.6 * 10^(-4)

Explanation:
The density is defined as the relation between the mass and the volume
First of all you need to have the same units for volume and density, so:
For the volume,
For the density,
From the density equation we have , so:
Answer:
a) 250 N/m
b) 22.4 rad/s , 3.6 Hz , 0.28 sec
c) 0.3125 J
Explanation:
a)
F = force applied on the spring = 7.50 N
x = stretch of the spring from relaxed length when force "F" is applied = 3 cm = 0.03 m
k = spring constant of the spring
Since the force applied causes the spring to stretch
F = k x
7.50 = k (0.03)
k = 250 N/m
b)
m = mass of the particle attached to the spring = 0.500 kg
Angular frequency of motion is given as
= 22.4 rad/s
= frequency
Angular frequency is also given as
= 2 π
22.4 = 2 (3.14) f
= 3.6 Hz
= Time period
Time period is given as
= 0.28 sec
c)
A = amplitude of motion = 5 cm = 0.05 m
Total energy of the spring-block system is given as
U = (0.5) k A²
U = (0.5) (250) (0.05)²
U = 0.3125 J
