Explanation:
Below is an attachment containing the solution.
Choice c) could represent the third step of inquiry.
Explanation:
Inquiry based learning is organized into inquiry phases.
The five general inquiry phase are
Orientation, conceptualisation, investigation, conclusion and discussion.
The investigation phase can be further divided into experimentation phase.
When Andrew washes three separate loads of dirty laundry ,one on hot setting,one one warm setting and one on cold setting , he is experimenting to collect data and interpreting it.
Only if he investigates will he know, which process will be suitable for doling out cleanest clothes.
Answer:
SI unit of k (spring constant) = N/m
Explanation:
We have expression for force in a spring extended by x m given by
F = kx
Where k is the spring constant value.
Taking units on both sides
Unit of F = Unit of k x Unit of x
N = Unit of k x m
Unit of k = N/m
SI unit of k (spring constant) = N/m
Answer:
4186 Joules
Explanation:
The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,
where
Q is the amiunt of heat needed
m = 1 kg is the mass
is the variation of temperature of the substance
For water, the specific heat capacity is 
. This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
The answer is D
Friction acts as a centripetal force in the case of a car turning. The friction creates a tangential force allowing the car to turn.
Tension can act as a centripetal force in the case of circles. Such as swinging a mass on a string, the tension force allows it to move in a curved path.
Gravity acts as a centripetal force in the case of satellites. The gravity keeps the satellite within the orbit.
