Modern fireplaces use a CATALYTIC COMBUSTOR to burn exhaust gases.
A catalytic combustor is an attachment which allows exhaust gases to be chemically broken down to release more energy. This is how it is applicable to modern fireplaces.
Answer:
The correct answer is "Evaporation of water from the soil will increase".
Explanation:
Evaporation is the step of the hydrologic cycle at which deposits of liquid water got into the atmosphere by transforming into a water vapor. The level of evaporation is closely related with the surface area of foliage, where the more surface area of foliage the less evaporation will occur. Therefore, if large areas of land experience clear-cutting, evaporation of water from the soil will increase.
While measuring , there are a lot of errors which can happen due to which ""true distances"" be different for different groups even though they are measuring the same distance.
While measuring , there are a lot of errors which can happen , to find the most correct value in order to make the result precise and accurate number of measurements needed to be done in order to reduce the error

Answer:
Viscosity of the fluid is
Explanation:
Given
- Length of the concentric cylinders, L=75 cm
- Gap between two concentric cylinders = 1 mm
- The frequency of inner cylinder = 300 rpm
- Torque acting
- Outer diameter of the inner cylinder=15 cm
The Area is given by
The velocity of the layer is layer is given by
Force acting by one layer of the fluid to other is given by F
Now from the Law of viscosity we have
Hence the viscosity of the fluid is
Answer:
1500 mph
Explanation:
Take east to be +x and north to be +y.
The x component of the velocity is:
vₓ = 889 cos 0° + 830 cos 59°
vₓ = 1316.5 mph
The y component of the velocity is:
vᵧ = 889 sin 0° + 830 sin 59°
vᵧ = 711.4 mph
The speed is found with Pythagorean theorem:
v² = vₓ² + vᵧ²
v² = (1316.5 mph)² + (711.4 mph)²
v = 1496 mph
Rounded to two significant figures, the jet's speed relative to the ground is 1500 mph.
