Which of the following is not a region of the brain?

Explain how living things such as people and trees are different from non living things such as rocks and tents

Musya8 [376]

The difference between living things and nonliving things is little things that we call is senses like sight, taste, touch, smell, and hearing. For example a human or animal can react to someone or something touching them. For a nonliving thing such as a rock can't react to someone touching them unless u force them to.

Early one October, you go to a pumpkin patch to select your Halloween pumpkin. You lift the 2.9 kg pumpkin to a height of 1.5 m

Katen [24]

Answer:

Work done in lifting to a height of 1.5 m is 42.63 J.

Work done in carrying it to 50 m is 0 J

Explanation:

Given:

Mass of the pumpkin (m) = 2.9 kg

Vertical displacement of the pumpkin (y) = 1.5 m

Horizontal displacement of the pumpkin (x) = 50 m

Acceleration due to gravity (g) = 9.8 m/s²

Work done by a force is given by the formula:

$W=FS\cos\theta$

Where,

$F\to force\ applied\\\\S\to displacement\ caused\\\\\theta\to angle\ between\ F\ and\ S$

Now, the work done is maximum when both force and displacement is in same direction. ( $\theta=0^\circ$ )
Work done is minimum when both force and displacement are in opposite direction. ( $\theta=180^\circ$ )
Work done is zero when force and displacement are perpendicular to each other. ( $\theta=90^\circ$ )

Here, as the pumpkin is raised to a height 'h', there is force applied against gravity in the upward direction. So, force and displacement are in same direction and thus the angle is 0° between the force and displacement vectors.

So, work done is given as:

$W=Force\times Vertical\ displacement$

Force applied is equal to the gravitational force applied by the Earth but in the opposite direction.

So, Force = mg = $2.9\times 9.8 = 28.42\ N$

So, work, $W=Fy=28.42\times 1.5=42.63\ J$

So, work done in lifting the pumpkin is 42.63 J.

Now, when the pumpkin is carried to the check-out stand, the displacement is horizontal while the force applied is still in the upward direction.

So, the force and displacement are perpendicular to each other. Thus, the work done is zero.

A mountain climber packs too much gear and finds it difficult to reach the summit before a storm blows in. How does this scenari

MissTica

As the climber climbs the mountain, he needs to over his or her own weight component along the slope of the mountains.

By Newton's second law: Net force = Mass x acceleration

Hence, greater the mass, greater will be the force required to move up the mountain. Hence, the climber will need to apply higher force to climb up as he or she has packed too much, which resulted in the increase in the mass. Hence, there is a increase in the force which will pull him or her downward.

ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.

A lamp is plugged into a standard 120-volt outlet. If the lamp draws a current of 0.5-amps, how much energy is consumed in 1 min

sergeinik [125]

One handy formula for electrical power ... the one that's
most helpful here ... is:

Power = (voltage) x (current).

so Power = (120 volts) x (0.5 ampere) = 60 watts.

Now 60 watts means 60 joules of energy per second.
In one minute, the lamp dissipates

(60 joules/second) x (60 seconds/minute) = 3600 joules/minute.
