Answer:
pretty sure for this one, "if the density affected the liquid's ability to retain heat."
Explanation:
a hypothesis should be in "if, then, because.." format, and while this bit of the passage doesnt include all three, it does include one! that bit of the passage would be an incomplete hypothesis.
When you are talking about calculating the kinetic energy of an object, the formula is as stated:
Ek =1/2mv²
Where m is mass and v is velocity. Sub all those numbers in and you'll get 25J of kinetic energy.
The goal of scientific method is to produce public knowledge. That is knowledge available to any person with sufficient education, all such knowledge can be verified by or deduced from experiments and observations.
Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.
Mango takes 1.009 seconds to reach the ground.
<h3>What is free fall ?</h3>
- A situation in which an object moves solely under the influence of gravity is referred to as free fall. An external force acts on the ball, causing it to move faster. This free fall acceleration is also known as gravitational acceleration. The term "free fall" refers to a downward movement with no initial force or velocity.

h =
where,
h = height = 5m ,
t = time ,
g =gravity = 9.8 m/s.
= 2h / g = 10/9.8 = 1.02
t= = 1.009 sec

Answer:
E= 8501.2
Explanation:
Given Data;
Speed = 10.6 km/s = 10.6*10^3 m/s
Magnitude = 0.802 T
The magnitude of the electric field is calculated using the formula;
q E = q v B
E = v B
= 10.6 *10^3 * 0.802
= 8501.2
The direction of the electric field will point along the negative z-axis
