1 answer:

7 0

1. Question : What part of the plant that transport water from its root to its leaves.
The answer is the stem. The stem connects the plant’s root and leaves, it is responsible for transporting water that is absorbed by the root going to the leaves, it is also responsible for transporting nutrients absorbed with the leaves coming from the sun or any nutrients going to the roots to make is grow faster and healthy. Stem is the one that connects leaves and root and the one the does the transporting job.

A cheetah of mass 68 kg can accelerate from rest to a speed of 20.1 m/s in 2.0 s. Assuming constant acceleration, what is the ne

Art [367]

Answer:

680 N

Explanation:

We start by calculating the cheetah's acceleration knowing that goes from rest (0 speed) to 20.1 m/s in 2 seconds:

$a=\frac{v_f-v_1}{t} \\a=\frac{20.1-0}{2} =10.05 \frac{m}{s^2}$

Now we use the definition of force (F):

$F=m*a\\F=68 kg * 10.05 \frac{m}{s^2} =683.4 N$

Therefore the force that accelerates the cheetah is 683.4 Newtons which we can round to 680 N to match the fourth choice shown

Answer:

$V=9.2565m/s$

Explanation:

From the question we are told that:

Force $F = 34 N$

Time $t = 0.6 s$

Length of pedal $l_p=16.5cm \approx0.165m$

Radius of wheel $r = 33 cm = 0.33 m$

Moment of inertia, $I = 1200 kgcm2 = 0.12 kg.m2$

Generally the equation for Torque on pedal $\mu$ is mathematically given by

$\mu=F*L\\\mu=34*0.165$

$\mu=5.61N.m$

Generally the equation for angular acceleration $\alpha$ is mathematically given by

$\alpha=\frac{\mu}{l}$

$\alpha=\frac{5.61}{0.12}$

$\alpha=46.75$

Therefore Angular speed is \omega

$\omega=\alpha*t$

$\omega=(46.75)*(0.6)$

$\omega=28.05rad/s$

Generally the equation for Tangential velocity V is mathematically given by

$V=r\omega$

$V=(0.33)(28.05)$

$V=9.2565m/s$

How fast is the relay stick moving relative to Ingrid

faust18 [17]

Assuming the speeds of both the stick and Ingrid are taken from a stationary point, the velocities of both Ingrid and the stick will be subtracted to see how much faster the stick is going. 16 - 9 = 7 km/h is the speed of the stick relative to Ingrid
