Answer:
im pretty sure it should be 50.0
Answer:
45 J
Explanation:
Assuming the level at which the ball is thrown upwards is the ground level,
We can use the equations of motion to obtain the maximum height covered by the ball and then calculate the potential energy
u = initial velocity of the ball = 3 m/s
h = y = vertical distance covered by the ball = ?
v = final velocity of the ball at the maximum height = 0 m/s
g = acceleration due to gravity = -9.8 m/s²
v² = u² + 2ay
0 = 3² + 2(-9.8)(y)
19.6y = 9
y = (9/19.6)
y = 0.459 m
The potential energy the ball will have at the top of its motion = mgh
mgh = (10)(9.8)(0.459) = 45 J
Hope this Helps!!!
According to the solving, the volume that this gold nugget occupies is 1.29 cm³.
<h3>What is volume?</h3>
Volume is a standard measure of three-dimensional space that is occupied. It is typically mathematically represented using standard or SI-derived units. Volume and the concept of length are connected. It is sometimes referred to as the object's capacity.
d= m/ V
m= dV
V= m/d
<h3>So according to the given data,</h3>
The mass of the gold nugget is 25 grams.
The density of gold is 19.32 g/cm³.
We know that,
m= Vd
To find out the Volume(V),
V= m/d
V= (25 g)/(19.32 g/cm³)
V= 1.29 cm³.
According to the solving, the volume this gold nugget occupies is 1.29cm³.
