Answer:
2.8 m 7.4 m/s
Explanation:
write all the values then use the equations of motion to find the distance and speed. please see attached photo
Answer:
D
Explanation:
It cannot be determined because the masses of the puck and stick are unknown.
Answer:
Explanation:
Initial magnetic flux = magnetic field x area
= 4.4 x 5 x 10⁻³
= 22 x 10⁻³ weber
Final magnetic flux
= 1.32 x 5 x 10⁻³
= 6.6x 10⁻³ weber
change in magnetic flux = 15.4 x 10⁻³
emf induced = change in flux / time
= 15.4 x 10⁻³ / 22 x 10⁻³
= .7 V
current in bracelet = emf / resistance
= .7 / .02
= 35 A
b )
power = volt induced x current
= .7 x 35
= 24.5 W .
162.2 J/s is the much power she use.
Since you did not include the choices, I am going to teach you the order of all the groups from letf to right on the periodic table.
The order from let to right is 1, 2, 3, 4, ...., 13, 14, 15, 16, 17, 18.
Group Family
1 Alakalyne metals is the group at the left end.
2 alkakalyne earth metals, is the next group from left to right
3 to 12 transition metals
3 scandium family
4 titanium family
5 vanadium family
6 chromium family
7 manganese family
8 iron family
9 cobalt family
10 niquel family
11 copper family (aka coinage metals)
12 zinc family (aka volatile metals)
13 boron family, aka icosagens
14 carbon family, aka crystallogens
15 nitrogen family, aka pnictogens
16 oxygen family, aka chalcogens
17 halogens
18 noble gases: is the group at the right end.
