Answer:
Explanation:
m = mass of the body
g = acceleration of gravity
h = height above surface of earth
m and g are constants while h can vary as the body is moving. Unless h is extremely large, you can take g to be a constant 9.81 m/s2
Weight is the measurement of the force of gravity, and it is mathematically defined as the mass of an object multiplied by gravitational acceleration: W = mg. On Earth, g is about 9.8 m/s². Rearranging the equation to find mass, m = W/g. Given our weight of 11000 N, the mass of the car would thus be m = 11000 N/9.8 m/s² = 1122 kg. So, the correct answer choice here would be B.
According to Jean Piaget, unrealistic idealism often occurs in adolescence as a result of egocentrism. Egocentrism is defined as the inability to understand or comprehend any point of view other than their own. Piaget claimed that adolescents are egocentric and are only seeing the world only from their personal point of view.
Answer:
the answer is radioactive dating
Answer:
A.88 feet per second.
B.96.56 km /hr
Explanation:
A
When converting from miles per hour to feet per second, we can use the following conversion factor.
1 mile per hour = 1.46667 feet per second.
Hence, 60 miles per hour will be = 60 X 1.46667 = 88 feet per second.
B.
Similarly, we can use the same process when converting from miles per hour to km per second.
1 mile = 1.60934 km
hence to convert we will multiply 60 miles/hour by 1.60934 km = 96.56 km /hr
