Energy of a random atomic and molecular is called molecules energy
Answer:
20m/s due east
Explanation:
Given parameters:
Displacement eastward = 200m
Time = 10s
Unknown:
Velocity = ?
Solution:
Velocity is the displacement divided by time;
Velocity =
Velocity =
= 20m/s due east
Transfer of heat through objects touching source
Explanation:
1) For a positive point charge, the lines radiate outwards
for a negative point charge, the lines converge inwards
2) F = 2.3 X 10^-26 N
k = 9 X 10^9 N.m²/C
q1 = q2 = e = 1.6 X 10^-19 C
r = ?
F = kq1q2/r²
r² = kq1q2/F
r = √[kq1q2/F ]
r = √0.0100
r = 0.10m
The two protons are 0.10 m apart
3) The unit if electric field intensity is Newton-per-coulomb N/C
The time taken before the two soccer players are 24.7 m apart is 3 seconds.
Velocity of Jane relative to marry is 4.4 m/s in y-direction and 6.95 m/s in x direction.
The distance between Jane and Mary after 4.08 seconds is 33.58 m.
<h3>
Resultant velocity of Mary and Jane</h3>
Vertical component of the velocity;
Jane: Vy1 = V sinθ
Vy1 = 5.07 m/s x sin(60.2)
Vy1 = 4.4 m/s
Horizontal components of the velocity;
Jane: Vx1 = V cos θ
Vx1 = 5.07 m/s x cos60.2
Vx1 = 2.52 m/s
mary: Vx2 = 4.43 m/s
total horizontal components of the velocity = 4.43 m/s + 2.52 m/s = 6.95 m/s
<h3>Resultant velocity</h3>
V = √Vy² + Vx²
V = √(4.4² + 6.95²)
V = 8.23 m/s
<h3>Time taken before they are 24.7 m apart</h3>
t = 24.7 m / 8.23 m/s
t = 3 seconds
Velocity of Jane relative to marry is 4.4 m/s in y-direction and 6.95 m/s in x direction.
<h3>Distance between Jane and Mary after 4.08 seconds</h3>
d = vt
d = 8.23 m/s x 4.08 s
d = 33.58 m
