Rudik [331]4 years ago

Answer: 2 seconds

Explanation:

We can solve the problem by using the following SUVAT equation:

S=\frac{1}{2}(u+v)t

where

S = 60 m is the distance covered

u = 10 m/s is the initial velocity

v = 50 m/s is the final velocity

t is the time taken

Re-arranging the formula and using the numbers above, we find the time taken:

t=\frac{2S}{u+v}=\frac{2\cdot 60 m}{10 m/s + 50 m/s}=2 s

An engineer weighs a sample of mercury (ρ = 13.6 × 103 kg/m3 ) and finds that the weight of the sample is 6.0 n. what is the sam
Amanda [17]
Given:
ρ = 13.6 x 10³ kg/m³, density of mercury
W = 6.0 N, weight of the mercury sample
g = 9.81 m/s², acceleration due to gravity.

Let V =  the volume of the sample.
Then
W = ρVg
or
V =  W/(ρg)
   = (6.0 N)/[(13.6 x 10³ kg/m³)*(9.81 m/s²)]
   = 4.4972 x 10⁻⁵ m³

Answer: The volume is 44.972 x 10⁻⁶ m³

Y_Kistochka [10]

Answer:

C)focusing on one goal at a time

Explanation:

Self-modification programs could be regarded as a program that help individual in managing unwanted as well as dysfunctional behavioral responses whenever they are going through a problem and try to deal with it. For instance the dysfunctional behavioral response for someone with a panic attack is avoidance. Some of the the steps that are involved in in a self-modification program are;

✓ specifying target behavior ✓designing a program

✓ gathering data about target behavior
