Since the car is driven 125km west and then 65km north, we simply add the two values together to get 190km
Answer:
a) 
b) 
Explanation:
From the question we are told that:
Width of diffraction grating 
Width of silt 
Distance 
a)
Generally the grafting element is the distance b/w the silts

Therefore the grafting element is

b)
Generally the equation for diffraction state is mathematically given by

Since

Therefore



Therefore orders observed with
is

A limestone plateau has no surface water. All the water is pulled underground through cracks and crevices in the surface. What most likely will cause the underground of the plateau to change over time?
Physical weathering due to frost wedging
Physical weathering due to abrasion
Chemical weathering due to oxygen
Chemical weathering due to water <em>Correct Answer</em>
Answer:
1. While boiling replace the cap and allow it to cool. Vapours inside condense and form water creating vacuum above them. Observation - The can crumbles due to air pressure from outside. This proves that air exerts pressure.
2. Measure the volume of the liquid displaced when the object is submerged. Measure the initial volume of water in graduated cylinder. Submerge the irregular object. Measure the final volume of the water.
— The difference between the initial volume and the final volume is the volume of the object.
