Valentin [98]3 years ago
5 0

Answer:

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.

Explanation:

In an alpha particle there are two protons

In the given substance's nucleus, there are total of 85 protons

After the decay, the proton number reduce

The current proton number after decay is

85 -2 = 83

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.

A horizontal surface of area 0.321 m2has an electric flux of 123 N.m2/C passing through it at an angle of 25° to the horizontal.
ValentinkaMS [17]

Answer:

electric filed is 907 N/C

Explanation:

Given data

surface of area = 0.321 m²

electric flux of 123 N.m²/C

angle = 25°

to find out

magnitude of the electric field

solution

we know flux formula that is

flux = electric filed × area

put all value

123 = electric filed × 0.321 sin(25)

electric filed = 123 /  0.321 sin(25)

electric filed = 906.67

so electric filed is 907 N/C

The only force acting on a 2.9 kg canister that is moving in an xy plane has a magnitude of 7.5 N. The canister initially has a
Elodia [21]

Answer:15.66 J

Explanation:

mass of block \left ( m\right )=2.9 kg

Force magnitude=7.5 N

Initial velocity =3.9\hat{i} m/s

Final velocity=5.1 \hat{j} m/s

Initial Kinetic Energy=\frac{1}{2}mv^2

=\frac{1}{2}\times 2.9\times 3.9^2=22.05 J

Final Kinetic Energy=\frac{1}{2}mv^2

=\frac{1}{2}\times 2.9\times 5.1^2=37.714 J

Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 J
