Answer:

The use of renewable sources of energy help to solve the problem of energy crisis is discussed below in details.

Explanation:

Environmental and economic advantages of adopting renewable energy incorporate: Creating energy that originates no greenhouse gas discharges from fossil fuels and decreases some kinds of air pollution. Increasing energy stocks and decreasing dependency on shipped fuels.

Here are 5 actionable suggestions you can follow to make a decent utilization of renewable energy on your bases:

Embrace Solar-Powered Technologies.
Crowdfund Clean Energy Projects.
Establish the Society of Concerned Scientists.

Maggie is using her cat in an experiment on animal intelligence. Which of the following statements is true?

Kamila [148]

1. If Maggie gives her cat an unfair advantage, her experimental results will be biased.

Explanation:

Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.

Due to her emotional attachment with the cat, the experimental results will be skewed to portraying her cat as intelligence.
This is not a good experiment to carry out.
Such an experiment should be carried out with an unknown cat.

A ball has a mass of 0.046kg. Calculate the change in gravitational potential energy when the ball is lifted through a vertical

loris [4]

Answer:

PE=0.92414J and KE=0.28175J

Explanation:

Gravitational potential energy=mass*gravity*height

PE=mgh

Data,

M=0.046kg

H=2.05m

g=9.8m/s^2

PE=0.046kg * 9.8m/s^2 * 2.05m

PE =0.92414J

KE=1/2mv^2

M=0.046kg

V=3.5m/s

KE=[(0.046kg)*(3.5m/s)^2]\2

KE=0.28175J

an ice skater starts with a velocity of 2.25 m/s in a 50.0 direction. after 8.33 m/s in a 120 direction. what is the y-component

Nata [24]

The y-component of the acceleration is $0.28 m/s^2$

Explanation:

The y-component of the ice skater acceleration can be calculated with the equation

$a_y = \frac{v_y-u_y}{t}$

where

$v_y$ is the y-component of the final velocity

$u_y$ is the y-component of the initial velocity

t is the time elapsed

Here we have:

Initial velocity is $u=2.25 m/s$ at $\theta_1=50.0^{\circ}$ , so its y-component is $u_y = u sin \theta_1 = (2.25)(sin 50.0^{\circ})=1.72 m/s$

Final velocity is $v=4.65 m/s$ at $\theta_2=120.0^{\circ}$ , so its y-component is $v_y = v sin \theta_2 = (4.65)(sin 120.0^{\circ})=4.03 m/s$

The time elapsed is

t = 8.33 s

Therefore, the y-component of the acceleration is

$a_y = \frac{4.03-1.72}{8.33}=0.28 m/s^2$
