Answer:
D is the correct answer
Explanation:
A) shows low accuracy and high precision since they missed the bull's-eye but are all grouped together.
B) Shows high accuracy and high precision
C) Shows high precision
D is the only one that shows both low accuracy and low precision
Explanation:
It is given that,
The ramp is tilted upwards at 25 degrees and Paul is pulling a large crate up the ramp with a rope that angles 10° above the ramp.
Total angle with respect to ramp is 35 degrees.
If Paul pulls with a force of 550 N.
The horizontal component of the force is given by :
![F_x=F\ cos\theta](https://tex.z-dn.net/?f=F_x%3DF%5C%20cos%5Ctheta)
![F_x=550\ cos(35)](https://tex.z-dn.net/?f=F_x%3D550%5C%20cos%2835%29)
![F_x=450.53\ N](https://tex.z-dn.net/?f=F_x%3D450.53%5C%20N)
The vertical component of the force is given by :
![F_y=F\ sin\theta](https://tex.z-dn.net/?f=F_y%3DF%5C%20sin%5Ctheta)
![F_y=550\ sin(35)](https://tex.z-dn.net/?f=F_y%3D550%5C%20sin%2835%29)
![F_y=315.46\ N](https://tex.z-dn.net/?f=F_y%3D315.46%5C%20N)
Hence, this is the required solution.
It’s carbon and it’s heat value
