Answer:
The explorer should travel to reach base camp to 5.02 Km at 4.28° south of due west.
Explanation:
Using trigonometric function like Sen(Ф), Cos(Ф) and Tan(Ф) we can get distance and direction that the explorer should travel to reach base camp. When we discompound the vector y
so that
;
to get how far we use Pythagorean theorem so
so that
Answer:
<h3>The answer is 5.4 kg</h3>Explanation:
The mass of the object can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>5.4 kg</h3>Hope this helps you
Answer:
a = 17.68 m/s²
Explanation:
given,
length of the string, L = 0.8 m
angle made with vertical, θ = 61°
time to complete 1 rev, t = 1.25 s
radial acceleration = ?
first we have to calculate the radius of the circle
R = L sin θ
R = 0.8 x sin 61°
R = 0.7 m
now, calculating at the angular velocity
ω = 5.026 rad/s
now, radial acceleration
a = r ω²
a = 0.7 x 5.026²
a = 17.68 m/s²
hence, the radial acceleration of the ball is equal to 17.68 rad/s²
The specific heat capacity of the substance is
Explanation:
When an object of mass m is supplied with a certain amount of energy Q, its temperature increases according to the equation:
where
m is the mass of the object
is its specific heat capacity
is the increase in temperature of the object
In this problem, we have
m = 50 g
Therefore, we can solve for to find its specific heat capacity:
