Answer:
Explanation:
Electric field strength, E = 5900 V/m
Magnetic field strength, B = 8.3 x 10^-3 T
The magnetic force on the charge particle is balanced by the magnetic force on the charge particle which is moving with velocity v.
qE = q v B
v = E / B

v = 7.1 x 10^5 m/s
Answer:
package will strike at a distance of 244.7 m
Explanation:
Given data;
Velocity of plane 45 m/s
Acceleration due to gravity 9.8 m/s^2
horizontal component of plane velocity is ux = 45 m/s
vertical component is zero
in the same way
ay = - 9.8 m/s^2
ax = .0 m/s^2
motion in y direction = -145 m
from equation of motion time of flight is


solving for t we get
t = 5.439 sec
Motion in x direction


s = 244.79 m
Therefore package will strike at a distance of 244.7 m
How do catalysts speed up reactions ?
by reducing the amount of energy required for the reaction to occur. other factors such as <span>catalysts' ability to speed a process are temperature, concentration </span>
Errrrr, it has 80.
80 is the correct answer
