Newtons first law of motion
object in motion stays in motion, object at rest stays at rest unless acted upon an unbalanced force
Responder:
Velocidad = 41.5m / s
Espacio recorrida = 352.5 metros
Explicación:
Dado lo siguiente:
Velocidad inicial (u) = 19.8 km / h
Aceleración (a) = 2.4m / s ^ 2
Tiempo de viaje (t) = 15 s
A.) velocidad después de 15 s
Velocidad inicial = (19.8 × 1000) m / 3600s Velocidad inicial = 19800m / 3600 = 5.5m / s
Usando la ecuación: v = u + at, donde v es la velocidad
v = 5.5 + 2.4 (15)
v = 5.5 + 36
v = 41.5m / s
Espacio recorrida:
v ^ 2 = u ^ 2 + 2aS; donde S es la distancia recorrida
41.5 ^ 2 = 5.5 ^ 2 + 2 × (2.4) × S
1722.25 = 30.25 + 4.8S
1722.25 - 30.25 = 4.8S
1692 = 4.8S S = 1692 / 4.8 S = 352.5m
Answer:
a. 1/1000 sec
Explanation:
Shutter speed is the length of time that the film you’re photographing is being exposed to the scene in film photography. However, in digital photography, shutter speed is the length of time that the image sensor sees the scene the photographer is trying to capture.
For shutter speeds, the greater the denominator the higher the speed and the lower the denominator, the lower the speed.
Thus, the fastest one is option A.
Answer:
Power is a scalar quantity and has a unit,a magnitude(a numerical value) but no direction.
Explanation:
Answer:
Thermal physics is the combined study of thermodynamics, statistical mechanics, and kinetic theory of gases. This umbrella-subject is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects. Other authors, however, define thermal physics loosely as a summation of only thermodynamics and statistical mechanics.
