The electromagnetic spectrum spans from radio waves to gamma rays. The picture provided illustrates this entire spectrum. However, the optical telescope is limited to observing only the visible spectrum, which ranges from 400 nm to 700 nm. This segment reflects the colors of ROYGBIV, with red exhibiting the highest frequency and violet the lowest frequency.
Answer:
11109.825 N
Explanation:
Provided Information:
mass = m = 1510 kg
initial acceleration (a) = 0.75g (where g = 9.81 m/s²)
Using the formula F=ma
= (1510)*(0.75*9.81)
= 11109.825 N
Answer:
All three pendulums will have the same angular frequencies.
Explanation:
For a simple pendulum, the time period using the approximation
is expressed as:

The angular frequency
is defined as

Since the angular frequency remains unaffected by the initial angle (valid strictly for small angle approximations), we deduce that the angular frequencies of the three pendulums are identical.

To solve this problem, we must ensure that the centripetal force equals or exceeds the gravitational force acting on the object. The formula for centripetal force is
F = mv^2/r
while the equation for gravitational force is
F = ma.
Since the mass (m) cancels out in both equations, we can equate them, leading to
a = v^2/r.
Now, inserting the given values (where the radius is half the diameter) allows us to find v:
9.8 m/s^2 <= v^2/1.5 m,
which simplifies to
14.7 m^2/s^2 <= v^2.
Therefore, we find that the minimum velocity required is 3.834057903 m/s <= v.
Thus, the necessary speed is 3.834 m/s.</span>
