Answer:
Explanation:
given,
Speed of a wave on violin A = 288 m/s
Speed on the G string = 128 m/s
Force at the end of string G = 110 N
Force at the end of string A = 350 N
the ratio of mass per unit length of the strings (A/G). = ?
speed for string A
.......(1)
speed for string G
........(2)
Assuming force is same in both the string
now,
dividing equation (2)/(1)
Answer:
Q = 266 Joules
Explanation:
Given the following data;
Mass = 20g
Initial temperature = 10°C
Final temperature = 29°C
Specific heat capacity of granite = 0.1 Cal/g°C to J/g°C = 0.7J/g°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
Substituting into the equation, we have;
Q = 20*0.7*(29-10)
Q = 14 * 19
Q = 266 Joules
0.51 m/s to the right.
<h3>Explanation</h3>The two carts lock together. As a result, the collision is inelastic. Kinetic energy will not conserve. Still, momentum conserves.
What's the momentum <em>p</em> of the two carts?
Before the collisions:
;
.
- Sum of momentum:
.
Momentum conserves. As a result,
Velocity is the same for the two carts after the collision. Let denote that velocity.
.
.
Direction of the movement will stay the same. Both cars are now moving to the right.
