negative peer influence
are
(1) 7.5 m/s vertical and 13 m/s horizontal
(2) 13 m/s vertical and 7.5 m/s horizontal
(3) 6.0 m/s vertical and 9.0 m/s horizontal
(4) 9.0 m/s vertical and 6.0 m/s horizontal
The components of the velocity are :
(2) 13 m/s vertical and 7.5 m/s horizontal
Vector is a quantity that has a magnitude and direction.
A vector in a cartesian coordinate is represented by an arrow in which the slope of the arrow shows the direction of the vector and the length of the arrow shows the magnitude of the vector.
A position vector of a point is a vector drawn from the base point of the coordinates O (0,0) to that point.
The addition of two vectors can be done in the following ways:
A negative vector is a vector with the same magnitude but in opposite direction.
Let's tackle the problem!
Given:
magnitude of the velocity = v = 15 m/s
direction of the velocity = θ = 60°
Asked:
horizontal component of the velocity = v_x = ?
vertical component of the velocity = v_y = ?
Solution:
Firstly , we will calculate the horizontal component of the velocity as follows:
Next , we will calculate the vertical component of the velocity as follows:

diffraction
Answer : diffraction
Explanation : Diffraction is the phenomenon of bending of sound waves around the small openings or obstacles.
Tierra is playing in her backyard when she hears her friend calling out to her. Tierra can hear her friend even when she can't see her. This is because the sound is spreading out from the small openings and hence diffraction of sound wave occurs.
212*f....... as that kid tried to explain the combustion process, and failed... the process isn't exactly the same for all heat engines... therefore, there has to be a universal heat that of in which has a standard heat of 212 degrees fahrenheit
(B) the object’s speed will decrease
(C) the object will follow a parabolic trajectory
(D) the object’s direction of motion can change, but its speed cannot
