An ice block will go further because there is less friction between the table and the ice. The brick has more friction, weight, and a gritty texture, so it won't make it as far. As for the ice block has less friction, a smoother surface, and a smoother texture which makes it have less friction.
Answer:
I believe it improves your hearts stroke volume
If im wrong plz let me know
In physics, force is equal to mass multiplied to acceleration. We are given that the mass is 0.25 kg and the force is 20 N.
F = ma
20 N = 0.25 kg * a
20 kg*m/s^2 = 0.25 kg * a
a = 20/0.25
a = 80 m/s^2
So the acceleration of the ball is 80 m/s^2.
Answer:
3100.05 N
Explanation:
= Force on piston = 45 N
= Radius of piston
= Radius of plunger
![\dfrac{r_2}{r_1}=8.3](https://tex.z-dn.net/?f=%5Cdfrac%7Br_2%7D%7Br_1%7D%3D8.3)
From Pascal's law we have
![\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}\\\Rightarrow F_2=\dfrac{F_1A_2}{A_1}\\\Rightarrow F_2=\dfrac{F_1\pi r_2^2}{\pi r_1^2}\\\Rightarrow F_2=\dfrac{F_1r_2^2}{r_1^2}\\\Rightarrow F_2=F_1\dfrac{r_2^2}{r_1^2}\\\Rightarrow F_2=45\times 8.3^2\\\Rightarrow F_2=3100.05\ N](https://tex.z-dn.net/?f=%5Cdfrac%7BF_1%7D%7BA_1%7D%3D%5Cdfrac%7BF_2%7D%7BA_2%7D%5C%5C%5CRightarrow%20F_2%3D%5Cdfrac%7BF_1A_2%7D%7BA_1%7D%5C%5C%5CRightarrow%20F_2%3D%5Cdfrac%7BF_1%5Cpi%20r_2%5E2%7D%7B%5Cpi%20r_1%5E2%7D%5C%5C%5CRightarrow%20F_2%3D%5Cdfrac%7BF_1r_2%5E2%7D%7Br_1%5E2%7D%5C%5C%5CRightarrow%20F_2%3DF_1%5Cdfrac%7Br_2%5E2%7D%7Br_1%5E2%7D%5C%5C%5CRightarrow%20F_2%3D45%5Ctimes%208.3%5E2%5C%5C%5CRightarrow%20F_2%3D3100.05%5C%20N)
The force is 3100.05 N
