The relationship between electricity and magnetism is called<span> electromagnetism.</span>
To find the impulse you multiply the mass by the change in velocity (impulse=mass×Δvelocity). So in this case, 3 kg × 12 m/s ("12" because the object went from zero m/s to 12 m/s).
The answer is 36 kg m/s
First recall the equation that relates frequency to wavelength:
v = fw
Note that the v is the speed of light, a constant. Now plug in the information we know!
(3×10^8) = (6.67 × 10^14) w
Hit the numbers on the calculator and you'll get the wavelength, w. If you comment your answer I'll check it for you. :)
Answer:
d. observing sunspots on the Sun and mountains on the Moon
Explanation:
Galileo was an Italian Physicist and Astronomer and is regarded as the father of modern Physics.
It was previously believed that the objects in the heavens such as the sun, moon and stars were perfect and rough till he observed sunspots on the sun and mountains on the moon which indicates the surface of the moon is rough with mountains and craters.
Draw a free body diagram to help you visualize. draw the object and use arrows to label and determine where all the forces acting upon it will be. then u add up the sum of all forces. if two forces of equal magnitude and opposite directions will cancel each other out.
