A 10-mL graduate weighs 42.745 g. When 5 mL of distilled water are measured in it, the combined weight of graduate and water is
Bingel [31]

Answer:

The measured weight of the water = 4.93 g

The percentage error in measured value = 1.4%

Step-by-step explanation:

Given:

Weight of the 10-mL graduate = 42.745 g

Combined weight of graduate and 5 mL water = 47.675 g

5 mL of water should weight = 5 g

thus, actual value of 5 mL water = 5 g

Now,

The measured weight of the water

= (Combined weight of graduate + 5 mL water) - Weight of the 10-mL graduate

= 47.675 g - 42.745 g

= 4.93 g

The percentage error in measured value

= \frac{\textup{Actual value-calculated value}}{\textup{Actual value}}\times100

= \frac{\textup{5-4.93}}{\textup{5}}\times100

or

= 1.4%

A block with a mass m = 5 kg slides down an inclined plane with an angle θ = 37°. The block maintains a constant acceleration a
OleMash [197]

Answer:1148.6 N

Step-by-step explanation:

Given

mass of block =5 kg

Inclination angle \theta =37^{\circ}

constant acceleration(a)=5.6m/s^2

\mu be the coefficient of kinetic friction =0.05

we know friction force=\mu N

forces acting on block is mgsin\thetadown the inclined  plane

friction force acting parallel to surface opposing mgsin\theta

Therefore

mgsin\theta - \mu N=ma

\frac{m\left ( gsin\theta +a\right )}{\mu }=N

N=\frac{5\left ( 9.81\times 0.6+5.6\right )}{0.05}

N=1148.6 N
