Answer : The correct option is, (D) Velocity includes rate of change and direction.
Explanation :
Speed : Speed is defined as the distance traveled by an object with respect to the time taken. It is a scalar quantity that means it tell us about the magnitude of an object not direction.
Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only.
Hence, the correct option is, (D) Velocity includes rate of change and direction.
Well i think it is false caus ebunch of products these day have metals incorparded in the product
0.29 m/s (wave velocity = wavelength (lamda)/period (T) in metres)
35 / 1.2 = 29.16
29.16 ÷ 100 = 0.29
Wave velocity in string:
The properties of the medium affect the wave's velocity in a string. For instance, if a thin guitar string is vibrated while a thick rope is not, the guitar string's waves will move more quickly. As a result, the linear densities of the two strings affect the string's velocity. Linear density is defined as the mass per unit length.
Instead of the sinusoidal wave, a single symmetrical pulse is taken into consideration in order to comprehend how the linear mass density and tension will affect the wave's speed on the string.

Answer:
105 mg
Explanation:
Given that:
1 baked potato provides 30 mg of vitamin C.
So,
70 baked potatoes provide
mg of vitamin C
Also,
70 potatoes = 20 lb
So,
20 lb potatoes provide
mg of vitamin C
Thus,
1 lb potatoes provide
mg of vitamin C
<u>Thus, 105 mg of Vitamin C are provided per pound of the potatoes.</u>
Because the fossil show layers and those layers show what kind of settlements where left behind at that layer
