Answer:
Because of less weight kick ball has more acceleration.
Explanation:
Acceleration of kick ball:
5 m/s
Acceleration of soccer ball:
3 m/s
Newton's second law:
According to newton's second law the acceleration of object depends upon two variables.
1) Mass of object
2) Force acting on it
Mathematical expression:
a = f/m
a = acceleration
f = force
m = mass
The force on balls are same thus the acceleration is depend upon the masses of balls.
The soccer ball has more weight that's why its acceleration is less while kick ball is lighter and thus its acceleration will more.
Two German chemists, Justus von Liebig (1803–1873) and Friedrich Wöhler (1800–1882), were responsible for the emergence of organic chemistry in the early nineteenth century. Their quantitative analytical methods helped establish the constitution of newly isolated and synthesized carbon compounds.
Answer:
14700J
Explanation:
From the question given, the following were obtained:
M = 100g
ΔT = 35° C
C = 4.2J/g °C
Q=?
The heat transferred can calculated for by using the following equation
Q = MCΔT
Q = 100 x 4.2 x 35
Q= 14700J
Answer: The given statement is true.
Explanation:
It is known that due to increase in temperature ice melts. Therefore, during ice age there is also melting of ice and solid state of water changes into liquid state of water.
Therefore, this water moves from its initial place and changes its position result in the change of land and specific areas.
Thus, we can conclude that the statement during an ice age, land can move and specific areas can be permanently changed is true.
