Answer:
Radius of curvature of the mirror = 250 cm
Explanation:
Given:
Object distance from mirror = 250 cm (u=-250)
Object distance appears in mirror = 250 cm (v=-250)
Find:
Radius of curvature of the mirror
Computation:
Using mirror formula
1/f = 1/v + 1/u
1/f = 1/(-250) + 1/(-250)
f = (-250/2)
f = -125 cm or 125 cm
Radius of curvature of the mirror = 2(f)
Radius of curvature of the mirror = 2(125)
Radius of curvature of the mirror = 250 cm
Answer:
Yes, the amount of Iron can affect the growth of plant.
Explanation:
Iron is essential micro-nutrient for the growth of plant but it is required only in small amount. Iron is required when plant produces chlorophyll and this gives plants oxygen and healthy green color but if a plant is suffering from iron deficiency then the plant's growth becomes stunted and leaves color changes to yellow. For plants requirement of iron is just 1 to 1.5 lb per acre whereas, requirement of nitrogen is 75 to 200 lb per acre.
Answer:
<em>Undergo global warming at a faster rate than what we are seeing currently</em>
Explanation:
Climate can be described as the average weather of a place. The climate of a particular place can be described after looking at the temperature of the place for a year or more.
If factors, such as the Sun and volcanoes controlled climates then there would be an increase in the temperature and more global warming. Volcanoes can be described as heat erupting from mountains which will, of course, lead to global warming.
Answer: number of bacteria
Explanation:
A easier way. I like to remember it is that x axis = independent and yaxis = dependent variable, but if that doesn’t help think about this
Why would the number of bacteria effect the amount of time. It doesn’t make sense because time goes on forever and nothing can change about it but time can change the number of bacteria because if you had a timer of 30 seconds and the bacteria is for example 10 and if you had a timer of one minute then the number of bacteria change because of time, if you flip it, it doesn’t make sense
