STALIN [3.7K]

Answer:

The angular displacement of each wheel is 269.92 rad

Explanation:

Given:

Angular acceleration $\alpha = 6.10 \frac{rad}{s^{2} }$

Time to pass cyclist $t = 4.36$ s

Angular velocity $\omega _{f} = 75.2 \frac{rad}{s}$

According to the equation of kinematics,

$\omega _{f} = \omega _{i} + \alpha t$

$\omega _{i} = \omega _{f} - \alpha t$

$\omega _{i} = 75.2 - 6.10 \times 4.36$

$\omega _{f} = 48.60$ $\frac{rad}{s}$

For finding angular displacement,

$\omega _{f} ^{2} - \omega _{i} ^{2} = 2 \alpha \theta$

Where $\theta =$ angular displacement,

$\theta = \frac{\omega _{f}^{2} - \omega _{i} ^{2} }{2\alpha }$

$\theta = \frac{5655.04 - 2361.96 }{2\times 6.10 }$

$\theta = 269.92$ rad

Therefore, the angular displacement of each wheel is 269.92 rad

an open cart is moving along a straight frictionless horizontal track. When rain starts falling vertically into the cart, what h

fgiga [73]

Answer:

The speed of the cart decreases

Explanation:

The track is frictionless, so we can consider the cart as isolated system (no external forces acting on it): therefore, the momentum of the cart is conserved

$p=mv=const.$

where m is the mass and v the speed of the cart.

When it starts raining, some water falls into the cart: this means that the mass of the cart, m, increases. But we said that the momentum, p, must remain constant: in order for that to happen, this means that the speed of the cart, v, must decrease (because the relationship $mv=const.$ is an inverse relationship, so if m increases, v must decrease).

Tanya [424]

Answer:

B. OSMOTIC PRESSURE WILL BE LOWER IN THE ARTERIOLE END OF THE CAPPILLARY BED COMPARED TO THE VENOUS END.

Explanation:

This is true for filtration to take place in the cappillary bed. Osmotic pressure is the net pressure that drives movement of fluid from the interstitial fluid back into the capillaries. Osmotic pressure increase favors reabsorption as water moves from region of higher water concentration in the interstitial fluid to the lower region of water concentration in the capillaries.

At the ends of a capillary bed, the difference in the hydrostatic and osmotic pressures provides a net filtration or reabsorption ratio. At the arteriole end of the capillary bed, hydrostatic pressure is greater than the osmotic pressure allowing movements of fluid to the interstitial fluid (filtration) while as the blood moves to the venous end, the osmotic pressure becomes greater than than hydrostatic pressure.
