Answer:
V=11.74m/s, 69.59°
Explanation:
From newtons equation of motion ,we know that
V^2 = u^2+2gh
for the rt
For the vertical component of the speed
Vy^2=V0^2+ 2gh
Vy= the final speed in the vertical axis
V0= initial speed, 0m/s
g= acceleration due to gravity 9.81m/s
h=height/distance between the eagle and the lake
Vy^2= 2*9.81*6.2
Vy =√121.644
Vy=11.02m/s
The resultant speed will be
V=(Vy^2+Vx^2)^0.5
V=(11.02^2+4.1^2)^0.5
V=137.7241^0.5
V=11.74m/s
Direction
Tan^-1(11.02/4.1)
β=69.59°
V=11.74m/s, 69.59°
Answer =11.74m/s, b°
Friction... Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
Means it will keep going until acted on by an outside force, in this case friction
Answer:
False
Explanation:
Think about every warning on electrical products, which is 'DO NOT KEEP NEAR WATER'
The coordinates of the image of point A of the dilated triangle becomes (3,3) where the image is from y axis.
<u>Explanation:</u>
Given-
scale factor = 2
length of base AB which corresponds the x axis is 1 unit
length of height BC which corresponds the y axis is 1 unit
Scale factor = new dimension/old dimension
For x axis-
2 = new dimension/ 1
new dimension for AB which corresponds the x axis is 2 units
For y axis-
2 = new dimension / y
new dimension for BC which corresponds the y axis is 2 units
The older coordinates for triangle ABC is (-2,2)
The new coordinates of the dilated triangle is (-3.3)
The coordinates of the image of point A of the dilated triangle becomes (3,3) where the image is from y axis.
The magnitude of the electrostatic force is 0.09 N, and the force is attractive
Explanation:
The strength of the electrostatic force acting on a charged particle is given by
where
q is the charge
E is the magnitude of the electric field
For the charge in this problem, we have:
is the electric field
is the charge
Therefore, the force experienced by this charge is
And the negative sign means that the force is attractive: in fact, the charge is negative, while the charge that is producing the field is positive (because the electric field points outward), therefore the negative charge is attracted towards the positive charge that is generating the field.
