The answer is D “the lake contains more mass and more heat than the cup of water”
It depends, one can be darker or lighter. There can be many colors of shade, there can also be different patterns of shade.
Answer:
The magnitude of the electric field is 8.47 N/C
Explanation:
Given;
uniform charge density, λ = 100 nC/m³
inner radii of the cylinder, r = 1.0 mm and 3.0 mm
distance from the symmetry axis, R = 2.0 mm
Area = 2πrl
Area =2π(2 x 10⁻)l
Volume = A x d
d = Volume / Area
the magnitude of the electric field
Therefore, the magnitude of the electric field is 8.47 N/C
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:
7 ms⁻¹
Explanation:
When the weight is 50% more, if the actual weight is W, the weight at the dip will be 1.5 Mg . At the bottom, the forces acting are
Weight Mg , vertically downwards
Centripetal force towards the center of the circle
and the normal force N = 1.5 Mg, that acts towards the center
N - Mg = Mv²÷ r
1.5 Mg - Mg = M v² ÷ r
0.5 g = v² ÷ 10
⇒ v = 7 ms⁻¹ Car's speed at the bottom of the dip.
