Average speed :
The horizontal (flat) line on a Distance - time graph shows that the body is at rest because the value of Distance (on y - axis ) is same for increasing time ( on x - axis ), it basically shows that the object is at the same position with the change in time.
therefore, correct option is :
Answer:
Explanation:
The simplest circuit has the battery in series with the resistor
V = IR
I = V/R = 1.5 / 15 = 0.10 Amps
It could be 1.5 / 150 = 0.01 A depending on how one assumes an error or not in "150hm"
Answer:
The average upward force exerted by the water is 988.2 N
Explanation:
Given;
mass of the diver, m = 60 kg
height of the board above the water, h = 10 m
time when her feet touched the water, t = 2.10 s
The final velocity of the diver, when she is under the influence of acceleration of free fall.
V² = U² + 2gh
where;
V is the final velocity
U is the initial velocity = 0
g is acceleration due gravity
h is the height of fall
V² = U² + 2gh
V² = 0 + 2 x 9.8 x 10
V² = 196
V = √196
V = 14 m/s
Acceleration of the diver during 2.10 s before her feet touched the water.
14 m/s is her initial velocity at this sage,
her final velocity at this stage is zero (0)
V = U + at
0 = 14 + 2.1(a)
2.1a = -14
a = -14 / 2.1
a = -6.67 m/s²
The average upward force exerted by the water;
Therefore, the average upward force exerted by the water is 988.2 N
A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm.
<h3>What is a triangle?</h3>
A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
In any triangle, the sum of two sides is always greater than the third side.
If the third side is equal to the sum of two sides then it will be a straight line rather than a triangle.
It means 10 + 14 > third side
24 cm > third side
Hence "A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm".
