Answer:
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.
Explanation:
Answer:
They must have been traveling at 5333.33 km/h to cover that distance in 3 days.
That speed are 6,66 times higher than the speed of an aircraft jet.
Explanation:
d= 384000 km
t= 3 days = 3*24hr = 72hr
V= 384000km/72hr
V= 5333.33 km/h
comparison:
V1/V2= 5333.33/800
V1/V2= 6.66
Answer:
B. -2
Explanation:
The total charge on an atom is the sum of all individual charges present in it. Therefore, the total charge on this atom is given by the following formula:
where,
q = total charge on atom = ?
= no. of protons in the atom = 15
= no. of electrons in the atom = 17
= no. of neutrons in the atom = 12
= charge on proton = +1
= charge on electron = -1
= charge on neutron = 0
Therefore,
Hence the correct option is:
<u>B. -2</u>
