This question involves the concepts of gravitational field strength and mass of the object.
The total weight of the bucket of oil is "54 N".
The gravitational field strength is defined as the weight of an object in the gravitational field per unit mass of the object. Hence, mathematically it can be written as follows:
where,
W = weight of the bucket of oil = ?
S = gravitational field strength = 10 N/kg
m = mass od the bucket of oil = 5.4 kg
Therefore,
<u>W = 54 N</u>

Answer:
The total amount of heat needed will be .
Explanation:
We will divide the calculation in two: First, the heat needed to melt the ice, and then the heat needed to warm the resulting liquid from 0°C to 37°C.
<em>i) </em>The fusion heat will be:
<em>ii)</em> The heat needed to warm the water from to
will be:
So, the total amount needed will be the sum of these two results:
.
Answer:
Car body rise on its suspension by 0.0309 m
Explanation:
We have given mass of the car m = 1500 kg
Mass of each person = 90 kg
Speed of the car
Distance traveled by car d = 3.7 m
So time period
Frequency
Angular frequency is
Angular frequency is equal to
k = 114109.92 N/m
Now weight of total persons will be equal to spring force
x = 0.0309 m
