Force vector is given as
now we need to find the magnitude of this force
as we know that
so here we will find the net force
so it is having magnitude as 35.2 N
Answer:
The average force exerted on the man by the ground therefore is 153.319.53 N
Explanation:
Given the following information
Mass of man, m = 75 kg
height of fall, h = 0.48 cm
velocity just before landing, v = 4.43 m/s
We therefore have
The work required to break the fall is equal to the kinetic energy of motion, just before touching the ground
Work done = Energy to absorb Kinetic Energy KE = 0.5·m·v²= F·h
Where:
F = Force required to break the fall
Therefore the force, F = (0.5·m·v² )/h
= 0.5×75 kg ×(4.43 m/s)²/(0.0048 m) = 153319.53 N
The average force exerted on him by the ground is therefore
= 153319.53 N.
Answer
given,
mass of the stick = 290 grams = 0.29 Kg
Force on the stick on one side = F = 9 N
force acting perpendicular to stick.
magnitude of acceleration
rate of change of angular momentum is equal to Force
rate of change of angular momentum = 9 N
F = m a
a = 31.034 m/s²
Direction of motion will in the direction of force application or in the direction of change of velocity
Niobium 97
Explanation:
When a substance undergoes beta decay, the mass number of such nuclei remains the same but the atomic number increases by 1.
A beta particle is denoted as ⁰₋₁β
Zirconium ₄₀⁹⁷Zr
Niobium ₄₁⁹⁷Nb
The decay reaction is shown below:
₄₀⁹⁷Zr → ₄₁⁹⁷Nb + ⁰₋₁β
From the equation above, we can deduce that both mass and atomic numbers are conserved;
Mass number: 97 = 97 + 0; 97 = 97
Atomic number: 40 = 41 - 1; 40 = 40

Answer:
snow
Explanation:
Since the process undergoes adiabatic expansion, hence q = 0 and ΔU = w.
We can sole this problem using the following derivation:
Since T2 = 265 K, we should expect a snow
