We know from the physics class that the time is simply the
distance divided by velocity:
time = distance / velocity
Substituting the given values and calculating for time:
time = 360 km / (72 km / hour)
time = 5 hours
<span>Therefore it takes the train 5 hours to arrive.</span>
Answer: the pair of sunglasses
Explanation:
A good pair of sunglasses are composed of abosorbent lenses that filter the sunlight that affects the eyes retina, especially ultraviolet (UV). So, these sunglasses are used to reduce the amount of light or radiant energy transmitted.
On the other hand, normal reading glasses (in which the lens glass has not been treated to filter ultraviolet sunlight) will let UV rays pass through.
Therefore, if both glasses are exposed to sunlight, the sunglasses are expected to be warmer by absorbing that radiant energy and preventing it from reaching the eyes.
Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the wagon is 12 kilograms and the acceleration is 3 meters per square second.
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second ( 1 kg*m/s²) is equal to 1 Newton (N)
- Our answer of 36 kg*m/s² is equal to 36 N
The force required for the 12 kilogram wagon to accelerate at 3 meters per square second is <u>36 Newtons.</u>
Answer:
Answer:
A. for every object submerged partially or completely in a fluid
Explanation:
This is following Archimedes principle which states that the upward buoyant force that is exerted on a body immersed in a fluid, whether FULLYor PARTIALLY submerged, is equal to the weight of the fluid that the body displaces.
