Answer:
the blood from carrying oxygen to the tissues of the body
Explanation:
we know that,
Frequency = 1/ time period
hence, Feq = 1/5 ===> 0.2 Hz
hence, wave velocity = freq * wavelength
hence,
V = 0.2 * 100
==> Wave velocity = 20 m/s
Answer:
atoms and molecules
Explanation:
as opposed to being continuous or just including particles). On the following page, the idea is stated as one of four concepts in Dalton's theory: “All matter is composed of tiny, indivisible particles called atoms”
The initial speed of the automobile is 49.84km/hr
<u>Explanation:</u>
Given:
Acceleration, a = 1.77 m/s²
Time, t = 6s
Final speed, v = 88 km/h
v = 88 X 0.278 m/s
v = 24.464 m/s
Initial speed, u = ?
We know,
v = u + at
On substituting the value in the formula we get:
24.464 = u + (1.77 X 6)
24.464 = u + 10.62
u = 24.464 - 10.62 m/s
u = 13.844 m/s
Converting u = 13.844 m/s to km/hr
1 m/s = 3.6 km/hr
13.844 m/s = 13.844 X 3.6 km/hr
u = 49.84 km/hr
Therefore, the initial speed of the automobile is 49.84km/hr
Increasing its velocity will add to the kinetic energy more as the formula for kinetic energy is 0.5*m*v^2. (The speed will be squared making it greater)
