Answer:
8 KJ/ s
Explanation:
Heat pumps Transfer thermal energy through absorbing of heat that comes from cold region and then release to warmer area by utilizing external power.
The coefficient of performance known as COP provide the ratio of both heating and cooling that are supplied to required work.
✓QH=The rate at which heat is produced = ?
✓COP= Coefficient of performance of a residential heat pump = 1.6
✓ W(in)= power consumption= 5KW
QH=The rate at which heat is produced=[Coefficient of performance of a residential heat pump] × [power consumption]
= 1.6 × 5KW
=8 KJ/ s
Answer:1855
Explanation:
Virchow in 1855 published the Omnis cellula e cellula which means cells arises from Pre existing cells.Virchow used this theory that cells arises from Pre existing cells to lay the groundwork for cellular pathology
Answer:
Explanation:
Energy stored in a capacitor
= 1/2 C₁V²
capacity of a capacitor
c = εK A / d
k is dielectric and d is distance between plates .
When the distance between the plates is halved and then filled with a dielectric (κ = 4.3)
capacity becomes 4.3 x 2 times
New capacity
C₂ = 8.6 C₁
Energy of modified capacitor
1/2 C₂ V²= 1/2 x 8.6 c x V²
Energy becomes
8.6 times.
Energy stored = 8.6 x 10⁻⁴ J
Hi there!
1. Weather is the condition in a day describing humidity, temperature, and rain or sun conditions. It also includes different features, including hail, snow, and storms.
2. Our atmosphere provides the air we need to breath. It also protects us from harmful UV rays from the sun, and it traps heat to ensure that the planet doesn't freeze.
3. We might have storms such as thunderstorms, or gusts of warm air coming our way. This is caused by the warm front.
4. Yes, it is possible that humans and dinosaurs drank the same water. Because of the water cycle and that water on earth never leaves the atmosphere since it is always cycled or recycled, it is possible that the same water, just in different states, have been in the mouth of a dinosuar.
Hope this helps!
The law of gravity because the closer it is, the greater the Sun's gravitational pull is.
