Answer:
23. Option B. Hertz
29. Refraction.
Explanation:
23. Determination of the unit of measurement of frequency.
Frequency is simply defined as the number of oscillation made in one second. Mathematically, frequency can be represented as:
Frequency = 1/period
f = 1/T
Period is measured in seconds.
Thus, the unit of frequency becomes
f = 1/T
f = 1/s = s¯¹ (Hertz)
Therefore, the unit of frequency is Hertz.
29. When a wave enters a new medium, the speed of the wave is uttered. This leads to the bending of the wave. When this occurs, we can say refraction has taken place.
Answer:
Pressure is equal in A, B, C and D
Explanation:
Pressure does not depends on the shape of the container
Pressure acting all direction
Answer:
His displacement is 260 – 169 = 91 km
His distance traveled is (260 – 134) + ( 169 – 134 ) = 161 km
Explanation:
Answer:
I think no because the critical properties distinguishing life is adaptation to changing environment and self replication of the information encoding the life process. Fire does not change its process to adapt to its environment, e.g. moving toward more fuel or storing and conserving fuel when it is in short supply.
Hope this help you!:)
The object is moving at a constant speed and towards the point of origin.
<h3>What is the distance time graph?</h3>
The distance time graph is used to show the relationship between the distance covered and the time taken. We know that the slope of the distance time graph is known as the speed of the object.
Given the fact that uniform or constant speed occurs when the distance is changing by equal amounts in equal time intervals, it is clear that is we have a straight line graph, the object is moving at a constant speed.
A good look at the graph as shown implies that the object is moving at a constant speed and towards the point of origin.
