Answer:
The Density of the block is 4.667g/mL
Explanation:
Given the following data;
Mass of block = 700g
Volume of block = 150cm³
Density = ?
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Substituting into the equation, we have;
<em>Density = 4.667g/mL</em>
Answer:
4. Downward and its value is constant
Explanation:
As this is a case of projectile motion, we use the reference frame where upward direction to be positive for , and in the same way to be negative in the downward direction. On another hand, we have that gravity is always acting this means that gravitational acceleration g is directed downward constantly over the dart not only during the upward but also during the downward part of the trajectory. And it is ruled by the following equations.
For the x-axis
For the y-axis
Where , is the initial velocity.
The mass of the block of ice is 2.24 kg
Explanation:
The amount of heat needed for the whole process consists of three different amounts of heat:
: the amount of heat needed to raise the temperature of the block of ice from
to
: the amount of heat needed to melt the block of ice at melting point
: the amount of heat needed to raise the temperature of the water from
to
The total amount of heat needed can be written as
where we have:
(total amount of heat required)
m is the mass of the block of ice
is the specific heat of ice
is the latent heat of fusion of ice
is the specific heat capacity of water
is the change in temperature in the 1st process
is the change in temperature in the 3rd process
Solving the equation for m, we find the mass of the block of ice:
