Answer:
1. Installing solar panels on the roof. This is an example of renewable energy, and solar panels help provide electricity for a home.
2. Using LED lights instead of traditional lightbulbs. The modern LED lights use much less electricity and function up to 90% more efficiently than the traditional lightbulbs.
3. Using rain barrels to collect water from the roof. Installing rain barrels to collect rainwater to water your plants and garden is a great way to save water and cut down on your water bill.
Hope this helps! :)
Answer:
the rigid outer part of the earth, consisting of the crust and upper mantle.
Explanation:
Acceleration=change in velocity divided by change in time or
we are given that it goes from 5m/s to 15m/s
in this case,
and the change in time or
is 1 second because this change occurs over a period of 1 second
so the acceleration is
the acceleration is
Answer:
0.9 s
Explanation:
Given (vertical direction):
y₀ = 4 m
y = 0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t
y = y₀ + v₀ t + ½ at²
(0 m) = (4 m) + (0 m/s) t + ½ (-9.8 m/s²) t²
t ≈ 0.9 s
Answer:
For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.
Explanation:
For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.
When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles increases, the space between the particles decreases, and the matter changes its state to solid.
