Answer: a i think hope this helps
Explanation:
Answer:
v = 23.66 m/s
Explanation:
recall that one of the equations of motion may be expressed:
v² = u² + 2as,
Where
v = final velocity (we are asked to find this)
u = initial velocity = 0 m/s since we are told that it starts from rest
a = acceleration = 0.56m/s²
s = distance traveled = given as 500m
Simply substitute the known values into the equation:
v² = u² + 2as
v² = 0 + 2(0.56)(500)
v² = 560
v = √560
v = 23.66 m/s
<h2>Answer to Q1: </h2>
<u>The correct option is </u><u>bat pushes on the ball with the same force as the ball pushes on the bat.
</u>
<h2>
Explanation:
</h2>
According to Newton’s law action and reaction are equal in magnitude but opposite in direction so the same case will apply here. The bat pushes on the ball with the same force as the ball pushes on the bat just the direction is opposite.
<h2>Answer to Q2
</h2>
Mass will remain the same
<h2>Explanation:
</h2>
The gravitational pull is related to the weight of objects. Weight is the force with which earth attracts everything towards its centre. And mass is the quantity of matter inside the body. So on the moon the quantity of matter inside a body does not change therefore the mass would remain the same.
<h2>Answer to Q3
</h2>
Force required is 16 Newton
<h2>Explanation:
</h2>
Mass= 80 kg
Acceleration = a = 0.2
So F = ma
Putting the values
F= 80 x 0.2
F = 16 N
The mineral with Mohs hardness would be scratched because the mineral with Mohs 7 hardness is stronger than the Mohs 5 mineral. Eventually, that mineral would turn into dust if you kept rubbing it.
A vector is a mathematical object that has both magnitude and direction. Both the vectors and analogue multimeter shows the magnitude as well as direction of the value that measures.
To find the answer, we have to know about the multimeters.
<h3>
How vector is analogous with multimeters?</h3>
- The formula for the magnitude of a vector, which may be written as |v|, can be used to determine the length of any given vector.
- In other words, this amount is used to specify the distance between the vector's beginning and ending points.
- The measurement of the angle produced using the horizontal line can be used to define the direction of a vector, which is nothing more than that.
- An analog multimeter is a particular kind of multimeter that measures electrical quantities including voltage, current, and resistance using a needle on a scale.
- A pointer that represents a particular value of the scale is used to display the result of any measurement made with an analog multimeter in analog form.
- The amount to be measured is shown by the scale's reading.
- The current value is shown by the needle's position on the scale.
Thus, we can conclude that, Both the vectors and analogue multimeter shows the magnitude as well as direction of the value that measures.
