Answer:

from W-Z.. i think on a swing you get your most potential energy at W and Z is where you go up so Z would be where the kinetic energy increased and W is where potential energy decrease

What is the volume of water in 150ml of the 35% w/w of sucrose solution with a specific gravity of 1.115?

pentagon [3]

Answer:108.71 mL

Explanation:

Given

Volume of sample V=150 mL

concentration of sucrose solution 35 % w/w i.e. In 100 gm of sample 35 gm is sucrose

specific gravity =1.115

Density of solution $\rho _s=1.115\times density\ of\ water$

Thus

$\rho _s=1.15\times 1 gm/mL=1.115\ gm/mL$

mass of sample $M=1.115\times 150=167.25\ gm$

mass of sucrose $m_s=0.35\times 167.25=58.53\ gm$

mass of Water $m_w=108.71 gm$

Volume of water $=108.71\times 1=108.781 mL$

Your neighbor Paul has rented a truck with a loading ramp. The ramp is tilted upward at 25°, and Paul is pulling a large crate u

Alisiya [41]

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 :

$F_x=F\ cos\theta$

$F_x=550\ cos(35)$

$F_x=450.53\ N$

The vertical component of the force is given by :

$F_y=F\ sin\theta$

$F_y=550\ sin(35)$

$F_y=315.46\ N$

Hence, this is the required solution.
