Calculate the momentum pelephant of a 2140 kg elephant charging a hunter at a speed of 7.63 m/s . pelephant= kg⋅m/s Compare the
1 answer:
Answer:
Momentum of elephant is greater than momentum of tranquilizer dart
Explanation:
= Mass of elephant = 2140 kg
= Mass of tranquilizer dart = 0.0415 kg
= Velocity of elephant = 7.63 m/s
= Velocity of tranquilizer dart = 619 m/s
Momentum of elephant
Momentum of tranquilizer dart
So,
Momentum of elephant is greater than momentum of tranquilizer dart

Answer:
Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/ (newtons per meter squared).
Answer:
distance r from the uranium atom is 18.27 nm
Explanation:
given data
uranium and iron atom distance R = 44.10 nm
uranium atom = singly ionized
iron atom = doubly ionized
to find out
distance r from the uranium atom
solution
we consider here that uranium electron at distance = r
and electron between uranium and iron so here
so we can say electron and iron distance = ( 44.10 - r ) nm
and we know single ionized uranium charge q2= 1.602 × C
and charge on iron will be q3 = 2 × 1.602 × C
so charge on electron is q1 = - 1.602 × C
and we know F =
so now by equilibrium
Fu = Fi
=
put here k = and find r
=
r = 18.27 nm
distance r from the uranium atom is 18.27 nm
