Newtons third law of motion states that for every action, there is an equal and opposite reaction
Calories would denote the amount of heat.
Givens are:
Mass = 500 g
t0 = 20C
tf = 30C
C = 1 cal/gC
Formula:
Q=MCt
500g (1cal/gC) 10C= 5000 cal

Answer:
1) henry moseley established a periodic table that arranges the elements by atomic number.
2) the atomic number increases from left to right on the periodic table.
3) metalloids have the characteristics of both metals and nonmetals.
Henry Gwyn Jeffreys Moseley (1887–1915) proposed that the number of positive nuclear charges (protons) in atom is equal to its atomic number in the periodic table.
Metalloids create a "staircase" down the periodic table.
For example, germanium (symbol: Ge) is a lustrous, hard, grayish-white metalloid in the carbon group.
Explanation:
Answer:
1.4 m/s
Explanation:
The final velocity of the ball can be found by using the following SUVAT equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
d is the distance travelled
In this problem,
u = 4.0 m/s
d = 14 m
a = -0.50 m/s^2
Solving the equation for v,
