Answer:
165.529454
Explanation:
According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.
Answer:
6.39 J of energy is needed to generate 0.71 * 10⁻¹⁶ kg mass
Explanation:
According to the Equation: E = mc²
where the mass, m = 0.71 * 10⁻¹⁶ kg
the speed of light, c = 3 * 10⁸ m/s
The amount of energy needed to generate a mass of 0.71 * 10⁻¹⁶ kg is calculated as follows:
E = (0.71 * 10⁻¹⁶) (3 * 10⁸)²
E = 0.71 * 10⁻¹⁶ * 9 * 10¹⁶
E = 0.71 * 9
E = 6.39 J
Answer:
Explanation:
Given
mass of skier=60 kg
distance traveled by skier=75 m
inclination![(\theta )=30^{\circ}](https://tex.z-dn.net/?f=%28%5Ctheta%20%29%3D30%5E%7B%5Ccirc%7D)
speed (v)=2.4 m/s
as the skier is moving up with a constant velocity therefore net force is zero
![F_{net}=0](https://tex.z-dn.net/?f=F_%7Bnet%7D%3D0)
Force applied by cable![=mg\sin \theta](https://tex.z-dn.net/?f=%3Dmg%5Csin%20%5Ctheta)
![F=60\times 9.8\times \sin (30)=294 N](https://tex.z-dn.net/?f=F%3D60%5Ctimes%209.8%5Ctimes%20%5Csin%20%2830%29%3D294%20N)
work done![=F\cdot x](https://tex.z-dn.net/?f=%3DF%5Ccdot%20x)
![W=294\cdot 75=22.125 J](https://tex.z-dn.net/?f=W%3D294%5Ccdot%2075%3D22.125%20J)
(b)Power![=F\cdot v](https://tex.z-dn.net/?f=%3DF%5Ccdot%20v)
![P=294\cdot 2.4=705.6 W\approx 0.946 hp](https://tex.z-dn.net/?f=P%3D294%5Ccdot%202.4%3D705.6%20W%5Capprox%200.946%20hp)
I think the answer is Snow flakes
