In the graph of the force vs the time:
Force is the gradient of the momentum versus the time.
If we get the area under the curve in this graph:
it will be calculated as : force * time
which gives the change in momentum or the impulse.
Therefore, the area under the curve <span>represents the impulse of the force in a graph of force versus time</span>
<span>Од сила е еднаква на масата * aceleration
Ние го имаме тоа сила = 5N, маса = 0.6kg a =?
5 = 0,6 * a.
Затоа a = 5 / 0,6
a = 8.33m / s²
Ве молиме да се одбележи мене како brainliest.</span>
Answer:
f = 0.4 Hz
Explanation:
The frequency of rotation of an object in order to achieve required centripetal or radial acceleration, can be found out by using the following formula:
f = (1/2π)√(ac/r)
where,
f = frequency of rotation = ?
ac = radial acceleration = 34.1 m/s²
r = radius = length of beam = 5.55 m
Therefore,
f = (1/2π)√[(34.1 m/s²)/(5.55 m)]
<u>f = 0.4 Hz</u>
Answer:
Explanation:
At the bottom the tension would be upwards and the weight downwards, their difference being the centripetal force. Taking the upwards direction as positive we then have:
where we have used the equation for centripetal acceleration. Thus we have:
Answer : B - real
Explanation : 1. you can see the image the way it is as in its no in a mirror.
2. The image will not be inverted
But it could be magnified too tbh. But I would go for real
