True. Mass is a constant does not change, regardless of where you are. It is your weight that changes based on the planet, so your weight on Earth and Saturn will not be the same, but your mass will be the same.
Answer:
The work done by Joe, W_joe, when he raises the barbell to finish one repetition is 211.98J
The correct option is Wsam <W_Joe.
Explanation:
From the mass of the bar, the acceleration of gravity and the distance that the bar travels in each of them when performing the lifting movement from the chest you can calculate the work done by each one:
W_joe= 31.5kg × 9.81 (m/s^{2} ) × 0.686m = 211.98J
W_sam= 31.5kg × 9.81 (m/s^{2} ) × 0.608m = 187.88J
187.88J < 211.98J ⇒ Wsam <W_Joe
Answer:When prfessionals take data collections its important becasue it can cause error. Lets say they are sloppy with thier work and end up getting something that is not near what should be happening. This can have a major affect on the truth of what they are doing and an effect on thier end result in general.

Answer:
The number of turns in the solenoid is 1.95 x 10⁴.
Explanation:
given information:
the length of solenoid, L = 0.34 m
magnetic field, B = 6.5 T
current, I = 90 A
to find the number of turn in solenoid, we can start from the magnetic field equation,
B = μ₀nI, n = N/L
B = magnetic field (T)
μ₀ = permeability (4π × 10⁻⁷ T.m/A)
n = the number turn per unit length (turn/m)
I = current (A)
N = the number turn in solenoid
L = the length of solenoid
thus,
B = μ₀IN/L
N = B L/μ₀I
= (6.5) (0.34)/(4π × 10⁻⁷) (90)
= 1.95 x 10⁴ turn
I would say B. A stable home and varied activities
