Answer:

A.compared

Explanation:

Fossils help figure out the time that organisms lived. If you know one of the fossils, it can be used as a reference for others around.

Physical data is often used in the court system. In fact, police officers use radar to determine your speed when you are driving
Mashcka [7]

The driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.

The given parameters:

  • <em>Speed of the driver observed by the stationary police officer, Vo = 44.7 m/s</em>
  • <em>Speed of the driver, V = 26.8 m/s.</em>
  • <em>Speed limit = 60 mph</em>

The speed limit of the driver in meter per second is calculated as follows;

= 60 \ \times \frac{miles}{hour} \times \frac{1609.34 \ m}{1 \ mile} \times \frac{1 \ hr}{3600 \ s}\\\\= 26.82 \ m/s

From the speed limit, it is obvious that the driver's speed is within the limit. Thus, we can conclude that the driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.

The roof of a two-story house makes an angle of 29° with the horizontal. A ball rolling down the roof rolls off the edge at a sp
AlekseyPX

Answer:

t = 0.93 s

Part b)

d = 3.98 m

Part c)

v_x = 4.28 m/s

v_y = -11.49 m/s

Explanation:

The two components of the velocity of the ball is given as

v_x = 4.9 cos29

v_x = 4.28 m/s

v_y = 4.9 sin29

v_y = 2.37 m/s

Part a)

now we know that the displacement in y direction is given as

\Delta y = 6.4 m

so we have

\Delta y = v_y t + \frac{1}{2}gt^2

6.4 = 2.37 t + 4.9 t^2

t = 0.93 s

Part b)

Distance of the ball in x direction of the motion is given as

d = v_x t

d = 4.28 \times 0.93

d = 3.98 m

Part c)

In x direction the velocity will remain the same always

v_x = 4.28 m/s

while in Y direction we can use kinematics

v_y = v_{oy} + at

v_y = -2.37 - 9.81(0.93)

v_y = -11.49 m/s

Water has a high heat capacity. What does this term mean? a) Water is relatively resistant to an increase in temperature. b) Wat
Delicious77 [7]

Answer:a) Water is relatively resistant to an increase in temperature

Explanation:

Water has relatively high heat capacity i.e. it requires high amount of heat to raise a little increase in temperature.

Heat capacity is defined as ability of molecule to absorb heat . Mathematically heat capacity is defined as

C=\frac{Q}{\Delta T}

where C=heat\ capacity

Q=heat\ interaction

\Delta T=change\ in\ Temperature
