Answer:
B energy can't be created or destroyed
Answer:
Explanation:
Kinetic energy can be found using the following formula:
where <em>m </em>is the mass and <em>v</em> is the velocity.
The mass of the ball is 0.5 kilograms and the velocity is 15 meters per second
Substitute the values into the formula.
First, evaluate the exponent.
- (15 m/s)²= (15 m/s) * (15 m/s) = 225 m²/s²
Multiply 0.5 kg by 225 m²/s²
Multiply 112 kg*m²/s² by 1/2, or divide by 2.
- 1 kg*m²/s² is equal to 1 Joule
- Therefore, our answer of 56.25 kg*m²/s² is equal to 56.25 Joules.
The kinetic energy of the ball is <u>56.25 Joules</u>
Answer:
6.1328 kg
60.16284 N
Explanation:
r = Radius of ball = 0.11 m
= Density of fluid = (Assumed)
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of ball
V = Volume of ball =
The weight of the bowling ball will balance the buouyant force
The mass of the bowling ball will be 6.1328 kg
Weight will be
A latitude called the Tropic of Capricorn, you could also put the southern hemisphere

<span>Negatively charged particles will go toward the positive end of the magnetic field and positively charged particles will go toward the negative end... for two reasons, because the positive is both repelled by the positive part of the field, and its also attracted by the negative end. oh, and on diagrams, the arrows of magnetic flux usually go from negative to positive.
Hope this helps(:</span>
