Answer:

Probably the more correct version of the story is that Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree.

irina [24]

Because the specific metals aren’t mentioned in this inquiry. The educational guesses that we can propose is that:
1. The hypothetical inquiry: There are existing metals for making pots that will cook food much faster.

2. The one-tailed alternative hypothesis: There are other metals for making pots that will cook food much faster than the other metals. 
3. The one-tailed null hypothesis: All metals that are used in making pots will cook food at an equal rate.

The motorcycle travels with a constant speed v0 along the path that, for a short distance, takes the form of a sine curve. Deter

Alexandra [31]

Let at any instant of time the speed is vo and the angle made by the bike with the horizontal is given

now we have

component of speed in x direction given as

$v_x = v_0cos\theta$

component of speed in y direction will be

$v_y = v_0sin\theta$

now from above two equations we can say that here

$\theta$ = angle with the horizontal at any instant

and since here it is a sine curve so we know that

$y = sin(x)$

so we have slope of graph

$tan\theta = \frac{dy}{dx} = cos(x)$

7. Describe about the difficultites that would arise due to lack of non-uniformity in measurement.

r-ruslan [8.4K]

Answer:

Many difficulties would arise if there was a lack of uniformity in the measurement of various weights and measures between business, industry, individuals and countries. The biggest implications for a lack of uniformity are in health and safety, equity and sustainability.

A block is thrown with an initial velocity of 30.0 m/s at an angle of 25.0o above the horizontal. What is the highest elevation

Serga [27]

The highest elevation reached by the ball in its trajectory is 16.4 m.

To find the answer, we need to know about the maximum height reached in a projectile.

What's the mathematical expression of the maximum height reached in a projectile motion?

The maximum height= U²× sin²(θ)/g
U= initial velocity, θ= angle of projectile with horizontal and g= acceleration due to gravity

What's the maximum height reached by a block that is thrown with an initial velocity of 30.0 m/s at an angle of 25° above the horizontal?

Here, U = 30.0 m/s and θ= 25°
Maximum height= 30²× sin²(25)/9.8

= 16.4m

Thus, we can conclude that the highest elevation reached by the ball in its trajectory is 16.4 m.
