Answer:
f = q
Explanation:
In the attachment we can see a diagram of the parallel rays.
The dotted line represents the normal to the mirror surface
These rays when reflected using the constructor equation
where p and q are the distance to the object and the image respectively.
Since the rays are parallel P = inf
1 / f = 1 / inf + 1 / q
f = q
this means that all the rays focus on one focal point.
<span>The velocity will be 41.25 m/s2 after 9 seconds. To find velocity after a specific time period, multiply the acceleration (2.75) times the number of seconds (9) to receive 24.75 m/s, then add that to the initial velocity of 16.5 m/s. 24.75 + 16.5 = 41.25 m/s2.</span>
This is a divergent plate boundary because the two tectonic plates are colliding together.
Answer:
F = 200 N
Explanation:
Given that,
Mass of the object, m = 20 kg
The acceleration of the object, a = 10 m/s²
We need to find the force exerted by the object. The force acting on the object is given by :
F = ma
So,
So, 200 N of force was exerted by the object.
Answer:
the dish's acceleration is 0.375 m/s^2.
Explanation:
Recall the formula from Newton's 2nd Law:
Force = mass x acceleration.
Since we know the force in the direction of the movement (0.15 N), and we know the mass of the object (0.4 kg) , its acceleration is given by:
acceleration = force / mass = 0.15 N / 0.4 kg = 0.375 m/s^2
