Answer:
Part a)
First image
second image
Part b)
First image
Second image
Explanation:
When object is placed between mirror and convex mirror
then for the first image
now from the mirror formula
here we have
For second position of image we will take object for convex mirror to be the position of image formed in plane mirror
so the distance of that image from convex mirror is
now by mirror formula
Part b)
Height of image and height of object is related by the equation
for height of second image
Answer:
true

Answer:
Impulse. Impulse is when a force is applied to an object for an amount of time.
Explanation:
It can't be momentum because momentum is the motion of a moving body, that is measured as a product of its mass and velocity.
It' cant be inertia because inertia is when an object doesn't move/ it does nothing as well as an object remaining unchanged.
And it can't be acceleration because acceleration is when how fast an object can go/ there velocity.
And that leaves us with impulse, so that's the correct one.
Hope this helped!
Answer: The answer is in the figure attached.
Explanation:
The Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the <u>International System of Units</u> is the Joule (J). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
However, in the British Engineering and Gravitational Systems its unit is Foot-pound (ft-lb). Where
Now, when the applied force is constant and the direction of the force and the direction of the movement (traveled distance) are parallel, the equation to calculate it is:
So, taking into account the explanation above, the attached table shows the Work done for each situation.
