If the acceleration constant..
you can use the formula s = ut + 1/2at²
Known that :
s = ?
u = 0
t = 2s
a = 10ms-²
Then you can apply the formula
s = ut + 1/2at²
s = 0 + 1/2(10)(2)²
s = 5 × 4
s = 20m
Answer : 20m
Explanation :
The gravity can be 9,8 or 10. Also im not sure how people teach you but in my school, if the ball goes down the gravity is positive and not negative thats why i put 10ms-² and not -10ms-²
s = displacement/distance
u = initial speed
a = acceleration
t = time
sorry if im wrong
Answer:
72 kg
Explanation:
The computation of the mass of the person is shown below:
As we know that
Water displaced weight = Raft weight + person weight
P_w.V = M_r + M_p
where
P_w denotes the water density i.e. 1000 kg/m^3
V denotes the volume of the water in m^3
Now
1000 × 0.224 = 152 + M_p
M_p = 224 - 152
= 72 kg
Arrhenius' equation relates the dependence of rate constant of a chemical reaction to the temperature. The equation below is the Arrhenius equation

where k is the rate constant, T is the absolute temperature. As the temperature of the system increases, the rate constant also increases and vice versa.
