Answer:
F = 50000 N
Explanation:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Given data:
Mass of car = 1250 Kg
Acceleration = 40 m/s².
Force = ?
Solution:
F = m × a
F = 1250 Kg × 40 m/s²
Kg.m/s² = N
F = 50000 N

Cobalt-59 is the only stable isotope of this transition metal. • Mass of proton = 1.00783 amu1.00783 amu
<h3>What is isotope ?</h3>
Isotopes are two or more atom types that share the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a given element are nearly identical, they differ in their atomic weights and physical characteristics.
The name "isotope" refers to the fact that different isotopes of a single element occupy the same location on the periodic table. The term "isotope" is derived from the Greek words isos ("equal") and topos ("place"), which together indicate "the same place." In 1913, Scottish physician and author Margaret Todd suggested the term to British chemist Frederick Soddy.
