Answer: 1 hour
Explanation: Focus on the units; 70 miles per hour means that each hour, you will travel 70 miles
or you can use the equation time = distance/speed. You have 70miles/ 70mph = 1hour
The distance is increasing as time passes.

<em>D. The object’s weight changes, but its mass stays the same.</em>
<u>Explanation;</u>
- Mass is the amount of matter in a object, which is measured in kilograms. Mass of an object is measured using a beam balance. It is important to note that the mass of an object or a body remains constant, and does not vary from one place to another. For instance the mass of a person on the moon will be the same as when the person is on the earth surface.
- Weight on the other hand is the measurement of gravitational pull of an object. weight is measured using a spring balance and measured in Newtons. Weight varies from one place to another depending on the gravitational pull of a given surface.

Answer:
The amount by which the second filter reduces the intensity of light emerging from the first filter is
z = 0.60
Explanation:
From the question we are told that
The angle between the axes is
The intensity of polarized light that emerges from the second filter is mathematically represented as
Where is the intensity of light emerging from the first filter
This means that the second filter reduced the intensity by z = 0.60
