Answer:
Yes, we must focus on p-value along with the alpha level
Explanation:
Alpha and P values are provides two different set of information. While on one hand alpha values sets an extreme value set before rejecting the hypothesis, P value determines the extremeness of the values in the data set. Thus, if p values is lesser than or equal to alpha value, the null hypothesis is rejected, If p value is greater than alpha value, then the null hypothesis is not rejected.
To calculate the average acceleration of the ball we use the formula,
Here, 
is the final velocity of the ball and 
is the initial velocity of the ball t is the time in contact with the wall.
Given 
towards the wall and 
away from the wall and 
.
Substituting these values in above formula , we get
Here is negative because ball is moving away from the wall.
Therefore, average acceleration of the ball is 
(away from the wall).
The velocity of projectile has 2 components, horizontal component vcosθ and vertical component vsinθ, where v is the velocity of projection and θ is the angle between +ve X-axis and projectile motion.
In case 1, θ = 90⁰
So horizontal component is vcos90 = 0
Vertical component at maximum height = 0
So velocity at maximum height = 0 m/s
In case 2, θ = 45⁰
So horizontal component is 141cos45 = 100m/s
Vertical component at maximum height = 0
So velocity at maximum height = 100 m/s
Answer:
D
Explanation:
descriptive, because scientists are writing down the observations but not making comparisons.
The speed of tsunami is a.0.32 km.
Steps involved :
The equation s = 356d models the maximum speed that a tsunami can move at. It reads as follows: s = 200 km/h d =?
Let's now change s to s in the equation to determine d: s = 356√d 200 = 356√d √d = 200 ÷ 356 √d = 0.562 Let's square the equation now by squaring both sides: (√d)² = (0.562) ² d = (0.562)² = 0.316 ≈ 0.32
As a result, 0.32 km is roughly the depth (d) of water for a tsunami moving at 200 km/h.
