Answer:
h = 1/2gt^2
Is the formula for the height of a free falling object.
Put in the numbers:
h = 1/2*9.8 (gravitational constant) * 10^2
h=490 meters.
Please note that the gravitational constant is approximate, you could also use a more specific value or 10
Answer:
a) Both have same angular speed
b) Mary has larger linear speed
c) Mary has larger radial acceleration
Explanation:
a) Since Tom and Mary are both on the same merry-go-around, all points on the merry-go-around are subjected to a same angular speed. Therefore, they both have the same angular speed.
b) Linear speed, however, is the product of angular speed and their radius or rotation, aka their distance the the center of rotation. In this case Mary has a larger radius since she's sitting at the outer rim.
c) Radical acceleration is the product of angular speed squared and their radius so again, Mary would have a larger radial acceleration because of greater radius.
Answer:
Torque on the coil will be ZERO
Explanation:
As we know that the magnetic moment of the closed current carrying coil is always along its axis and it is given as
now we know that magnetic field is also along the axis of the coil so here as we know the equation of torque given as
so we have
<span>Possible explanation one would be people are outdoors more due to the use of the snow blower and are thus more susceptible to falling as a result if the increased time spent near or on the ice. Possible explanation two is the snow that's removed from their sidewalk can no longer provide a traction surface between the people clearing the snow and the ice that lies beneath the snow. And possible explanation number three would be that the snow blowing machine, being a new piece of equipment to people, requires a level of agility to operate and inexperienced operators lack the agility to use the piece of equipment.</span>
