Answer:
Transverse
Explanation:
There are two types of waves, depending on the direction of the oscillation:
- Transverse wave: in a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave - examples of transverse waves are electromagnetic waves
- Longitudinal wave: in a longitudinal wave, the direction of the oscillation is parallel to the direction of motion of the wave - examples of longitudinal waves are sound waves
Radio waves are a type of electromagnetic waves - consisting of oscillations of electric and magnetic field that propagate in a vacuum at the speed of light - so they are an example of transverse wave.
Answer:
B
Explanation:
A detailed solution to the problem is shown in the image attached. You could study it. The half life, and percentage of C-14 compared to present living sample was given as 13% of that of a living sample.
The property that compares the mass of an object with its volume is density.
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer: its speed upon release is 26.05 m/s
Explanation:
Given that;
mass m = 0.244 kg
force F = 30.3 N
V1 = 14.7 m/s
r = 59.3 cm = 0.593 m
Vf = ?
we know that;
1/2mV1² + FπR = 1/2mVf²
so we substitute
[1/2×0.244×(14.7)²] + [30.3×π×0.593 = 1/2×0.244×Vf²
26.3629 + 56.4478 = 0.122Vf²
82.8107 = 0.122Vf²
Vf² = 82.8107 / 0.122Vf
Vf² = 678.7762
Vf = √678.7762
Vf = 26.05 m/s
Therefore its speed upon release is 26.05 m/s
