Answer:
Answer: It allows people to rapidly heat items
Hope this helps!
Explanation:
Answer:
There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
Horizontal component:
x(t) = 5t + 6t²
x(5) = 25 + 6(25) = 175 m
Vertical component:
y(t) = 7 - 3t³
y(5) = 7 - 3(125) = -368 m
Components combined:
r(5) = (175 m) i - (368 m) j
Taken relative to the point r(0) = (0 i + 7 j) m ,
the displacement vector when t=5 is
(175 m) i - (375 m) j .
Its magnitude is √(175² + 375²)
= √(30,625 + 140,625)
= √171,250 = 413.823... m (rounded)
Its direction is tan⁻¹(-375/175) = tan⁻¹(-2.14285...) = - 64.98°
Answer:
There will be no change in the angular momentum of the system.
Explanation:
Total angular momentum of the system will remain unchanged . We can apply law of conservation of momentum because no external torque is acting on the system . There is increase in the momentum of inertia due to dropping of ball of putty . In order to conserve angular momentum , the system decreases its angular velocity . Hence the final angular momentum remains unchanged .
False, in a collision a vehicle that rebounds off the object it strikes does not experience less force than if it crumples assuming the time is the same in both situations.
