Answer:
The distance traveled by the balloon is 10.77 m
Explanation:
velocity of the ball, = 2 m/s south
velocity of the air, = 5 m/s west
To determine the distance the balloon will travel after 2 seconds, first determine the resultant velocity of the balloon.
| 2m/s

↓
5m/s ←------------------
the two velocities forms a right angled triangle and the resultant will be the hypotenuses side of the triangle.
R² = 5² + 2²
R² = 29
R = √29
R = 5.385 m/s
The distance traveled by the balloon is calculated as;
d = R x t
where;
t is time of the motion = 2 seconds
d = 5.385 x 2
d = 10.77 m
Therefore, the distance traveled by the balloon is 10.77 m.
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 amplitude and wavelength are measured in meters while frequency is measured in decibels.
<h2>
Units of measurement:</h2>
- Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.
- Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.
- Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.
- Wave speed: It is measured in m/s.
- Loudness: The loudness of the sound is measured in decibels.
Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

Put the fish in another small bowl of water. Empty the tank, rinse it, and fill it with new water and the right amount of conditioner. Let it get to the right temperature for the fish, then gently put the fish back in it. And FAST ! All of this is very stressful for the fish.
Solar energy is one of the renewable energy sources that is invested around the world because of its large potential. the sun as a free source can sometimes bring a drawback. one of the drawbacks is that it cannot be harnessed when storms or rains are present in the weather. it is also expensive and young.
