Answer:

Neutrons have mass values close to proton mass values. Approximately the mass of a resting neutron is 1.674 928 x 10 ^ -27 kg.

Explanation:

Neutrons are atomic particles, ie they are part of the composition of atoms. Neutrons were first identified in 1932 by the English physicist James Chadwick (1891-1974). This scientist was conducting experiments with radioactivity when he found the presence of a particle that had no electric charge, he named it Neutron (zero charge).

The name could not be more appropriate since the lack of electric charge makes this particle neutral. It is present in the nucleus of the atom along with the protons (which have a positive charge). Neutrons have mass values close to those of the proton mass. Approximately the mass of a resting neutron is 1.674 928 x 10 ^ -27 kg

lara [203]

Answer:

given,

mass of the skier = 70.1 Kg

angle with horizontal, θ = 8.6°

magnitude of the force,F = ?

a) Applying newton's second law

$m g sin\theta - F_{rope} = ma$

velocity is constant, a = 0

$m g sin\theta - F_{rope} =0$

$F_{rope} = m g sin\theta$

$F_{rope} = 70.1\times 9.8\times sin 8.6^0$

$F_{rope}= 102.73\ N$

b) now, when acceleration, a = 0.135 m/s²

$F_{rope}-m g sin\theta = ma$

velocity is constant, a = 0.135 m/s₂

$F_{rope} = m g sin\theta+ma$

$F_{rope} = 70.1\times 9.8\times sin 8.6^0+70.1\times 0.135$

$F_{rope}= 112.19\ N$

If an automobile battery is rated at 20 ampere-hours, what is the maximum current that can be supplied for 19 minutes?

Elenna [48]

20Ah is the number of charge that can be supplied at 20A for 1 hour. If you wish to drain it in 19 minutes, then the current is:
$20*60 = A_{2}*19$
$A_{2}=63.2A$
