Answer:
1.3 L
Explanation:
The volume of a rectangular cube can be calculated using the following formula:
Volume (L) = length (cm) x width (cm) x height (cm)
Keep in mind that 1 L = 1,000 cm³.
Before you can plug the values into the equation, you need to make sure they all have the same unit. Since the length is in meters (m), you need to first convert it to centimeters.
1 meter = 100 cm
0.159 m 100 cm
--------------- x ---------------- = 15.9 cm
1 m
Now, you can solve for the volume. To find the answer is the unit liters, you need to divide the volume by 1,000.
Volume = l x w x h
Volume = 15.9 cm x 10.5 cm x 7.7 cm
Volume = 1,285.5 cm³
Volume = 1.2855 L ------> Volume = 1.3 L
The IUPAC says that elements have to be named after one of five things: a scientist, a place, a mineral or substance, a descriptor of the element, or a mythological reference. Of the new elements, three are named after places and one is named after a person No-one has yet named an element after themselves but many elements are named in tribute to important scientists

Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force
N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
