Which of the following is the most effective way for humans to reduce biodiversity loss?

ANTONII [103]

Answer:

Creating large preserves in biodiversity hotspots

Explanation:

In order to preserve the biodiversity hotspots, humans must create biodiversity hotspots which are regions that will nurture, preserve and protect the species from the danger of going extinct in the wild or being hunted by other predators or men.

There will help protect them from dangers and improve the biodiversity of the planet. It will add to the ecological productivity of the environment.

A home uses ten 100-watt lightbulbs for five hours per day. Approximately how many kilowatt-hours of electrical energy are consu

timurjin [86]

The electrical energy consumed in one year by using the light bulbs is 8,760 kWh.

The given parameters:

Number of light bulbs = 10
Power consumed by each bulb = 100 W
Time of energy consumption, t = 1 year

<h3>What is electrical energy?</h3>

This is the electric power consumed or dissipated at a given period of time.

The electrical energy consumed in one year by using the light bulbs is calculated as

E = Pt

$E = (100 \times 10) \times (1 \ yr \times \frac{8760 \ hrs}{1 \ yr} )= 8,760,000 \ W att-hours\\\\
E = \frac{8,760,000 }{1000} = 8,760 \ kWh$

Thus, the electrical energy consumed in one year by using the light bulbs is 8,760 kWh.

Brian Berg of lowa built a house of cards 4.88 m tall. Suppose Berg throws a ball from ground level

Step2247 [10]

Answer:

Vf = final velocity = 1.96 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

$v_{f}^{2}=v_{o}^{2}-2*g*x$

where:

Vf = final velocity [m/s]

Vo = initial velocity = 9.98 [m/s]

g = gravity acceleration = 9.81 [m/s²]

x = vertical distance [m]

$v_{f}^{2}=(9.98)^{2}-2*9.81*4.88\\v_{f}^{2} = 99.6-95.74\\v_{f}=\sqrt{3.8544}\\v_{f}=1.96[m/s]$

Note: The negative sign of the gravity acceleration means that the gravity acceleration is pointing in the opposite direction of the movement.
