Answer:
Specific heat capacity means that in order to raise copper by 1C per kg, it needs 380J of heat energy.
Answer:
protons (+ charge) & neutrons (neutral charge)
however protons has a positive charge so it determined what atom it is.
Answer:
t = 1.58 s
Explanation:
given,
Speed of ranger, v = 56 km/h
v = 56 x 0.278 = 15.57 m/s
distance, d = 65 m
deceleration,a = 3 m/s²
reaction time = ?
using stopping distance formula
t is the reaction time
t = 1.58 s
hence, the reaction time of the ranger is equal to 1.58 s.
If my math is right its A) 7
because 189 divided by 27 is 7
People, and cars
is the right answer!!!!!!!!!!!!!!!!!!!!!!!!!!
