Answer:
A 1 horsepower motor with 75% effiency will require 994. 26 watt
Explanation:
To calculate the effiency, 1 horsepower is equivalent to 745.7 watts
1hp= 745.7 w
So, by using a rule of three the calculation its like this:
745.7 ⇒ 100%
X ⇒ 75%
The information about the volts in this example is not required, but it can be used to calculate the current.
Answer:
A)Temperature at which liquid starts to become gas.
Explanation:
Boiling point is the temperature at which a liquid boils and turns to vapour or gas.
From the law's of physics, we can know about the different boiling points for different liquids. As an example: at 100 °C temperature the water starts to change into the vapor. It's the boiling point of the water.
Mass=highest of neutron almost same of proton and mass of electrons is 1/1840 of protons the charge on neutron is neutral positive on Proton and negative on electrons Neutron and protons are inside the nucleus and keep the electron orbiting around them in different shells..
Ideal Mechanical Advantage (IMA) can be found by using the formula:
IMA = ID/OD
ID = Input Distance
OD = Output Distance
In the question, we are given:
ID = 150
OD = 75
Now, solve the expression with what we have.
IMA = 150/75
IMA = 2
Therefore, the IMA is 2.
Best of Luck!
Answer:
Explanation:
We need to use the momentum and energy conservation.
Where:
- m is the mass of bullet (m=0.01 kg)
- M is the mass of the wooden (M=0.75 kg)
- v(0) initial velocity of bullet
- V(1) is the velocity of the combined object in the moment the bullet hist the block
Conservation of energy.
We have kinetic energy at first and kinetic and potential energy at the end.
Here:
- V(1) is the velocity of the combined at the initial position
- h is the vertical height ( h = 0.800 m)
We can find V(2) using the definition of force at this point:
Now, we can solve the equation to find V(2)
Now we can find V(1) using the conservation of energy equation
Finally, using the momentum equation we find v(0)
I hope it helps you!
