Answer:D - adding a catalyst
Explanation:
True
Explanation:
When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.
This very correct.
- When electricity is used in a sustainable way, there is little of it consumed.
- Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
- Less coal and fuel would be used and power plants do not need to produce as much electricity.
- Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
- When these appliances are turned off, less energy is in demand and less will be produced.

Answer:
λ = 0.45×10⁻⁶ m
Explanation:
Given data:
Wavelength of blue light = ?
Frequency of blue light = 6.69×10¹⁴ s⁻¹
Solution:
Formula;
Speed of wave = wavelength × frequency
Speed of wave = 3.00×10⁸ m/s
by putting vales,
3.00×10⁸ m/s = λ × 6.69×10¹⁴ s⁻¹
λ = 3.00×10⁸ m/s / 6.69×10¹⁴ s⁻¹
λ = 0.45×10⁻⁶ m
Isn't this a math problem?
If it is the the answer should be 102.
10 decimeters=1 meter
27x10=270
270-168=102
Answer: the answer is c.The unbalanced push causes the cart to speed up.
Explanation:
The application of an unbalanced force (the push) causes the cart to speed up. When the cart is in constant motion, the forces are balanced and there is no speeding up. Once an unbalanced force is added, the cart's speed changes.
